Question

7) ABCD is a quadrilateral with A= C and B = D. If A is twice B, find the measure of each angle. ​

Answer 1

Step-by-step explanation:

So A = 2B

A = C = 2B

If B = D then A = 2D = 2 B

So

A+B+C+D = 360 ( Angle Sum property)

2B + 2B + B + B = 360

6B = 360

B = 360/6

B = 60 A = 2B = 120 C = 2B = 120 D = 60
