Question

if WISE is a parallelogram and angle W = 90° , then prove that WISE is a rectangle....
pls give an explanation.....​

Answer 1

Answer:

Step-by-step explanation:If WISE is a parallelogram , and W=90° then the opposite angle S=90° as opposite angles of a parallelogram are equal.There fore if 2 angles in a quadrilateral are 90 then the other 2 angles are also 90° as sum of angles in a quadrilateral are 360°.Therefore WISE is a rectangle.

Answer 2

angle opposite of parallelogram is equal so w=s=90

and I=E

also , sum of alternate angles is 180

w+I=180

I=90

so , w= I=s=e

and opposit sides are parallel and equal... hence it is rectangle
