NCERT Solutions for Class 9 Maths exercise 9.1 - The properties of parallelograms on the same base and between the same parallels are identified in NCERT solutions for Class 9 Maths chapter 9 exercise 9.1. It includes questions about the diagonal of a parallelogram, its base, side lengths, area, and other unique properties of parallelograms. More such properties of this geometric shape are addressed in this NCERT exercise. Class 9 Maths chapter 9 exercise 9.1 two shapes are stated to be on the common base and between the same parallels if: A side is common between two shapes. The vertices opposite the same side and the sides parallel to the common base are both on the same straight line parallel to the base.

If two shapes are congruent then the amount of area occupied by them will also be equal but the vice-versa of this statement is not true i.e. two figures having the same area need not be congruent.
A parallelogram is a geometrical shape with sides that are parallel to each other in two dimensions. It's a four-sided polygon (also known as a quadrilateral) with two parallel sides that are the same length. A parallelogram's interior opposite angles are also equal. The sum of a parallelogram's adjacent angles is 180 degrees.
Answer:
In figure (i), (iii) and (v) we can see that. they lie on the same base and between the same parallel lines.
In figure (i) figure (iii) figure (v)
Common base DC QR AD
Two parallels DC and AB QR and PS AD and BQ
Area of the parallelogram are equals if they have a common base and between the same parallel line. We can also prove this property mathematical because we know that formula of the area of a parallelogram is the product of base and height. Since we have a base in the same and the distance between two parallel lines remains the same so the height is also the same.
The same theorem also applies to the triangles. Triangles with an equal area are those that have the same or common base and are connected by the same parallels.
