Question

In a quadrilateral ABCD angleA=45°, angleB=135° and angleC = angleD. Find the measures of angleC. ​

Answer 1

Answer:

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

45°+135°+ angle C+ angle D= 360°

Angle C+ angleD= 360°-180

angleC and angle D=180°

180/2=90°

so both angle C and angle D are same measure of 90°

Answer 2

angle a = 45degree

anglr b = 135degree
