Question

In the parallelogram ABCD angle A is 55 find all the other angles (simple steps please)

Answer 1

Step-by-step explanation:

angle A = angle = C = 55° (opposite Angeles of parallelogram)

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

55°+55°+angle B + angle D = 360°

110°+angle B+angleD = 360°

(but here angle B = angle D)

110°+2× angle B = 360°

2×angle B = 360°-110°

2 × angle B = 250°

angle B = 250°/2

angle B = 125°

angle C = angle B = 125°
