Question

Explain step by step

Answer 1

Hi there!
Here's the answer.

Step-1 :
Prove that the figure is a parallelogram.
There are 5 different ways to prove that this shape is a parallelogram.
Choose one of the methods.
- Show that both pairs of opposite sides are congruent.
- Show that both pairs of opposite sides are parallel.
- Show that one pair of sides is parallel and congruent.
- Show that the diagonals bisect each other.
- Show that the opposite angles are congruent.


In this example, sweet chikki,

If any of the method is satisfied, then ABCD is a parallelogram.
( say vertices of chikki be A, B, C & D)

Step-2 :
Next, prove that the parallelogram is a rectangle.
We can do this by showing that that the diagonals are congruent or by showing that one of the angles is a right angle.
It may be easier to show that one of the angles is a right angle.

If it is also satisfied, then ABCD is a rectangle


;)
hope it helps
