## Practical Geometry Class 8 NCERT Solutions (Intext Questions and Exercise)

Class 8 practical geometry NCERT Solutions - Chapter: Introduction

Answer: No, he cannot construct a unique quadrilateral. The given measurements consist of 2 adjacent sides, the angle between these sides and 2 diagonals. It is not one of the specific combinations to construct a quadrilateral.

Moreover, on trying to construct using these, we find that the vertex C is not fixed and can be varied. Hence, the quadrilateral is not unique.

NCERT Solutions for Class 8 Maths Chapter 4 Practical Geometry - Topic: Constructing A Quadrilateral

Q (i) We saw that 5 measurements of a quadrilateral can determine a quadrilateral uniquely. Do you think any five measurements of the quadrilateral can do thisAnswer: No, any five measurements of the quadrilateral cannot determine a quadrilateral uniquely. For example, consider a quadrilateral ABCD where AB, BC, CD are known and $\angle$ A and $\angle$ C are known. But this cannot uniquely determine the quadrilateral.

Answer: Yes, we can draw a parallelogram BATS where BA = 5 cm, AT = 6 cm and
AS = 6.5 cm (diagonal). We know, diagonals of a parallelogram are equal. Hence, BT = AS =6.5 cm
And opposite sides are equal. Hence, BS =AT = 6 cm;
Therefore, we have 2 diagonals and 3 sides to construct the parallelogram uniquely.
Answer: Yes, we can draw a rhombus ZEAL where ZE = 3.5 cm, diagonal EL = 5 cm.
Because all sides of a rhombus are equal.
Therefore we have four sides and a diagonal to construct the rhombus uniquely.

Q (iv) A student attempted to draw a quadrilateral PLAY where $PL = 3 cm, LA = 4 cm, AY = 4.5 cm, PY = 2 cm$ and $LY= 6 cm$ , but could not draw it. What is the reason?
[Hint: Discuss it using a rough sketch].
Answer: Given, a quadrilateral PLAY where $PL = 3 cm, LA = 4 cm, AY = 4.5 cm, PY = 2 cm$ and $LY= 6 cm$ ,

Rough sketch:

We know, that sum of two sides of a triangle must be greater than the third side. But PL + PY < YL . Hence this is not a triangle. Therefore, this quadrilateral cannot be made.

AB = 4.5 cm
BC = 5.5 cm
CD = 4 cm

OR = 6 cm
RE = 4.5 cm
EO = 7.5 cm

We know, Opposite sides of a parallelogram are equal in length and also parallel to each other

Therefore,

EM = OR = 6 cm,

Practical geometry class 8 questions and answers - Topic: When Two Diagonals And Three Sides Are Given

Answer: No, it is not possible. We cannot draw $\Delta$ ABD first, because neither SSS nor SAS condition is there.

Answer: Yes, we can construct a quadrilateral with the given conditions. Here, two diagonals and three sides are given.

(Hint: Construct $\Delta PRS$ using SSS condition. Next, find point Q by drawing arcs from P and R. PQRS is the required quadrilateral.)

Class 8 maths chapter 4 question answer - Exercise: 4.2

LI = 4 cm

IF = 3 cm

TL = 2.5 cm

LF = 4.5 cm

IT = 4 cm

LI = 4 cm

IF = 3 cm

TL = 2.5 cm

LF = 4.5 cm (Diagonal)

IT = 4 cm (Diagonal)

Steps of construction:

Rhombus BEND
BN = 5.6 cm
DE = 6.5 cm

Answer: Given, BEND is a rhombus.

BN = 5.6 cm (Diagonal)
DE = 6.5 cm (Diagonal)

We know that the diagonals of a rhombus bisect (cut in halves) each other at 90 degrees.

Steps of construction:

Step 1. Draw a line segment BN = 6.5 cm. With radius greater than half of BN, draw arcs on both sides of BN with B and N as the center. The line joining these two intersections is the perpendicular bisector of BN. Let it intersect BN at O (Therefore, O is the midpoint of BN. It will also be the midpoint of DE!)

Step 2. With O as the center, draw two arcs on the perpendicular bisector with radius = $\frac{1}{2} DE = \frac{6.5}{2} = 3.25 cm$ (Since, O is the midpoint of DE.)

Step 3. The intersecting points are vertices D and E.

Step 4. Join D to B and N. Also join E to B and N.

BEND is the required rhombus.

NCERT Class 8 maths ch 4 question answer - Topic: When Two Adjacent Sides And Three Angles Are Known

Answer: Yes, we can draw the quadrilateral MIST if we have 100° at M instead of 75°. (It will be a different quadrilateral!)

Moreover, The vertex T will now change. And since the sum of all interior angles of a quadrilateral is 360°, hence angle T will also change.

We know that sum of all the interior angles of a quadrilateral is 360°.

$\therefore$ ∠P + ∠L +∠A + ∠N= 140° + 75° + 150° + ∠N = 360°

$\implies$ ∠N = 360° - (140° + 75° + 150°) = - 5°

But this is not possible, because an angle of a quadrilateral cannot be negative.

Hence, We cannot construct a quadrilateral PLAN.

Answer: Yes, we still need at least the measure of the angle between the two adjacent sides to create a unique parallelogram.

Class 8 maths Chapter 4 NCERT Solutions - Exercise: 4.3

MO = 6 cm
OR = 4.5 cm
∠M = 60°
∠O = 105°
∠R = 105°

MO = 6 cm
OR = 4.5 cm
∠M = 60°
∠O = 105°
∠R = 105°

Rough:

Steps of construction:

Step 1. Draw a line segment MO = 6 cm. Construct an angle of 105° at O. As OR =4.5 cm, draw an arc with O as centre and radius = 4.5 cm. We get point R.

Step 2. Construct an angle of 105° at R.

Step 3. Construct an angle of 60° at M. This ray intersects the previous one at E.

PL = 4 cm
LA = 6.5 cm
∠P = 90°
∠A = 110°
∠N = 85°

PL = 4 cm
LA = 6.5 cm
∠P = 90°
∠A = 110°
∠N = 85°

We know, Sum of all angles of a quadrilateral = 360°

$\therefore$ ∠P + ∠L + ∠A+ ∠N = 360° $\implies$ 90° + ∠L + 110° + 85° = 360°

$\implies$ ∠L = 360° - 285° = 75°

Steps of Construction

Step 1. Draw a line segment PL = 4 cm. Construct an angle of 75° at L. As LA =6.5 cm, draw an arc with L as centre and radius = 6.5 cm. We get point A.

Step 2. Construct an angle of 110° at A.

Step 3. Construct an angle of 90° at P. This ray intersects the previous one at N.

Parallelogram HEAR
HE = 5 cm
EA = 6 cm
∠R = 85°

Answer: Given, HEAR is a parallelogram.
HE = 5 cm
EA = 6 cm
∠R = 85°

We know, Diagonally opposite angles of a parallelogram are equal.

Therefore, ∠E = ∠R = 85°

And, Opposite sides of a parallelogram are equal and parallel to each other.

Therefore, AR = HE = 5 cm
RH = EA = 6 cm

Steps of construction:

Step 1. Draw a line segment HE = 5 cm. Construct an angle of 85° at E. As EA = 6 cm, draw an arc with O as center and radius = 6 cm. We get to point A.

Step 2. With A as centre, draw an arc of radius = AR = HE = 5 cm.

Step 3. With H as centre , draw an arc of radius = HR = EA = 6 cm. The intersection of this arc with the previous arc is R.

Step 4. Join R to H and R to A.

HEAR is the required parallelogram.

Alternatively,

Steps of construction

Step 1. Draw a line segment HE = 5 cm. Construct an angle of 85° at E. As EA = 6 cm, draw an arc with O as center and radius = 6 cm. We get to point A.

Step 2. Construct an angle of (180°-85° = 95°) at A. (Adjacent angles in a parallelogram are supplementary)

Step 3. Construct an angle of (180°-85° = 95°) at H. This ray intersects the previous one at R.

HEAR is the required parallelogram.

Q1 (iv) Construct the following quadrilaterals.

Rectangle OKAY
OK = 7 cm
KA = 5 cm

Answer: Given, OKAY is a rectangle.
OK = 7 cm
KA = 5 cm

We know that all four angles of a rectangle are right angles ( $90^{\circ}$ ) and opposite sides are equal

Therefore, OK = AY = 7 cm. KA = YO = 5 cm

Steps of construction:

Step 1. Draw a line segment OK = 7 cm. Construct a right angle at K. With K a center, draw an arc of radius = 5 cm. We get to point A.

Step 2. Construct another right angle at A. With A as the center, draw an arc of radius = AY =OK = 7cm. We get the point Y.
