Using opposite angles test for parallelogram , prove that every rectan

1.	Using opposite angles test for parallelogram , prove that every rectangle is a parallelogram.
Answer» we can easily prove that ABM ≡ CDM using the SAS congruence test. (alternate angles are equal). Hence, ABCD is a parallelogram, because one pair of opposite sides are equal and parallel. Thereafter, ABCD is also a rectangle, because it is a parallelogram with one right angle it's not right because one pair is also parallel in trapezium

Answer»

we can easily prove that ABM ≡ CDM using the SAS congruence test. (alternate angles are equal).

Hence, ABCD is a parallelogram, because one pair of opposite sides are equal and parallel.

Thereafter, ABCD is also a rectangle, because it is a parallelogram with one right angle

it's not right because one pair is also parallel in trapezium
