Class 9 Maths Exercise 8.2 Question 1 Solution
Class 9 Maths Exercise 8.2 Question 2 Solution

We have seen that in a parallel quadrilateral, each pair of opposite sides is equal. Further, we also know that if each pair of opposite sides of the quadrilateral is equal, then it is a parallel quadrilateral. We can conclude the same result for couples of opposite angles that in the parallelogram, the opposite angles are the same.

We have studied many properties of a parallel quadrilateral in Grade 9 Math Chapter 8. Here, we can say that a quadrilateral is a parallelogram if a pair of opposite sides are equal and parallel.

We have studied many properties of a triangle and a quadrilateral. Now let’s examine another result that is related to the midpoint of the sides of a triangle. Do the following activity.
