Question

two adjacent angles of a parallelogram are congruent .what is the measure of each?​

Answer 1

Answer:

Here, two adjacent angles are congruent, which means that they are equal. Taking the measure of each congruent angle to be x°, we get x°+x°=180° Hence, 2x°=180° On symplifying, x=90° Therefore the measure of each angle of the parallelogram is 90°

Answer 2

Answer:

two adjacent angles are congruent, which means that they are equal. Taking the measure of each congruent angle to be x°, we get x°+x°=180° Hence, 2x°=180° On symplifying, x=90° Therefore the measure of each angle of the parallelogram is 90°
