Straight angle = 180 degrees and right angle = 90 degrees.

Acute angle: When an angle is smaller than a right angle, we call it an acute angle.

Obtuse angle: When an angle is bigger than a right angle but smaller than a straight angle, we call it an obtuse angle.

Reflex angle: When an angle is larger than a straight angle, we call it a reflex angle.

** Q1 ** What is the disadvantage in comparing line segments by mere observation?

** Answer: **The disadvantage in comparing line segments by mere observation is that our estimation may be inaccurate and therefore a divider must be used.

** Q2 ** Why is it better to use a divider than a ruler, while measuring the length of a line segment?

** Answer: **While measuring the length of a line segment using error might creep in due to the thickness and translucency of the ruler and because of angular viewing. We can get rid of these errors using a divider.

[Note : If A,B,C are any three points on a line such that AC + CB = AB, then we can be sure that C lies between A and B.]

** Answer: **

Yes

** Answer: ** AB = 5 cm

BC = 3 cm

AC = 8 cm

Therefore AB + BC = AC

Therefore point B lies between points A and C.

** Q5 ** Verify, whether D is the midpoint of AG.

** Answer: ** AD = 4 - 1 = 3

DG = 7 - 4 = 3

Therefore, AD = DG

Therefore, D is the midpoint of AG.

** Answer: ** To Prove

B is the midpoint of AC

C is the midpoint of BD

From (i) and (ii) we can conclude

Hence proved.

** Answer: **

After measuring their sides we have found that the sum of lengths of any two sides of a triangle is always greater than the third side.

**Understanding Elementary Shape Class 6 Maths Chapter 5-Summary**

In Class 6 Maths Chapter 5, "Understanding Elementary Shapes," the following topics are covered:

Measuring Line Segment: This topic focuses on measuring the length of a line segment using a ruler or a measuring scale. Students learn how to read measurements in centimeters (cm) and millimeters (mm) and understand the concept of units of length.

Angles - 'Right' and 'Straight': Students are introduced to angles and learn about two specific types: right angles and straight angles. A right angle measures exactly 90 degrees and forms the shape of an "L." A straight angle measures exactly 180 degrees and forms a straight line.

Angles - 'Acute', 'Obtuse', and 'Reflex': This topic expands on angles by introducing acute angles, which are less than 90 degrees, and obtuse angles, which are greater than 90 degrees but less than 180 degrees. Students also learn about reflex angles, which measure greater than 180 degrees but less than 360 degrees.

Measuring Angles: Students explore how to measure and draw angles using a protractor. They understand that the measure of an angle is represented in degrees and learn how to determine the measurement of an angle accurately.

Perpendicular Line: This topic introduces the concept of perpendicular lines. Students learn that perpendicular lines are two lines that intersect at a right angle, forming four right angles at the point of intersection.

Classification of Triangles: Students learn about the classification of triangles based on their sides and angles. They study equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).

Quadrilaterals: This topic focuses on quadrilaterals, which are polygons with four sides. Students learn about different types of quadrilaterals, such as squares, rectangles, parallelograms, and trapezoids. They understand the properties and characteristics of each type.

Polygons: Students delve into the concept of polygons in general, which are closed figures formed by line segments. They explore the properties of polygons and study various types, including triangles, quadrilaterals, pentagons, hexagons, and so on.

Three-Dimensional Shape: This topic introduces three-dimensional shapes, also known as solid shapes. Students learn about common three-dimensional shapes like cubes, cuboids, cylinders, cones, and spheres. They understand the distinguishing features and characteristics of each shape.

1. What is the number of corners in a triangular prism?

A triangular prism has six corners, also known as vertices. In a triangular prism, there are three vertices at the top triangle and three vertices at the bottom triangle. These vertices are connected by edges to form the prism.

2. What is the measure of each angle of a rectangle?

In a rectangle, each angle measures 90 degrees. A rectangle is a quadrilateral with four right angles (90-degree angles). The opposite sides of a rectangle are parallel, and all four angles are equal, measuring 90 degrees each. This property of rectangles makes them useful for various geometric and architectural applications. Students can study understanding elementary shapes class 6 pdf after downloading form the website.

3. A triangle is having three equal sides. What is the measure of their angle?

If a triangle has three equal sides, it is called an equilateral triangle. In an equilateral triangle, all three angles are equal. Since the sum of angles in any triangle is always 180 degrees, each angle of an equilateral triangle measures 60 degrees. Also these concepts are discussed in class 6 maths chapter 5 pdf which can be downloaded from careers360 website.
