Question

ABCD is a rectangle. Find the measure of Angle A

Answer 1

Answer:

m(Angle A) = 90°

Step-by-step explanation:

In rectangle ABCD ,

All angles of a triangle is equal

Therefore, Let the common angle be x

Angle A +Angle B + Angle C + Angle D = 360°

x+x+x+x =360°

4x = 360°

x = 90°

Therefore m(Angle A) = 90°
