think how mid point theorm can be proved

Midpoint Theorem, which states that **The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side**." EF is parallel to QR. So, EF is half of QR

Recall what have you learnt about various quadrilaterals so far.
