RS Aggarwal Solutions Class 8 Maths Chapter 16 Parallelograms – Overview

You must know the key points of RS Aggarwal Solutions Class 8 Maths Chapter 16 before you start preparing for your Class 8 Maths exam.

• All angles of the parallelogram sums up to 360 degree. 

The point A,B,C and D represent a parallelogram 

∠A+∠B+ ∠C+∠D= 360 

1. Theories of parallelogram 

2. Opposite sides of parallelogram are equal.

3. Opposite angles of parallelogram are equal. 

4. Diagonals bisect each other. 

• Congurance of triangles: The triangles are congruent if the sides of the respective triangles superimpose the sides of the other sides. 
• The side of one of the triangles is equal to the corresponding side of the other triangle.

To prove the congurance of triangles, there are various theories, mentioned below:

• SSS – In this, the side of one triangle is equal to the other triangle’s side. In triangle ABC and PQR, 

AB= PQ 

BC= QR 

AC= PR 

• SAS – In this, one side is equal to the corresponding side, the angle is equal to the corresponding angle, and side to the other triangle’s side. In triangle ABC and PQR,  AB= PQ 

∠B= ∠Q

BC= QR 

• ASA – In this, angle is equal to the corresponding angle of the triangle, and side is equal to the corresponding angle of the triangle. 

For example, In triangle ABC and PQR, 

∠B= ∠Q

BC= QR 

∠C= ∠R

• AAS – In this, two angles are equal to the corresponding angle and the side is equal to the side. 

For example, In triangle ABC and PQR, 

∠A= ∠P

∠B= ∠Q

AB= PQ 

• HL – This applies to the right angle, In this, the hypotenuse of one right-angled triangle is equal to the other, and any of the other sides is equal to the side of the other right-angled triangle. For example, In right-angled triangle ABC and PQR, 

AC= PR

BC= QR
