Activity 1: Proving Midpoint Result For Quadrilaterals
Task No. 1
In the figure, PQRS is formed by joining the midpoints of a quadrilateral ABCD. Prove that PQRS is a parallelogram.
(Hint: Use the result of the Midpoint Theorem - The line joining the midpoints of two sides of a triangle is parallel to the third side and half of it.)
