Question

Two adjacent angles are equal. is it necessary that each of these angles will be a right angle? justify your answer.

Answer 1

No it is not necessary.
Two angles are said to be adjacent when they have common vertex, a common side but do not overlap. They can be of any measure. For example, 33° and 25° can be two adjacent angles.

Answer 2

Answer:

No, it is not necessary that two adjacent angles which are equal will form a right angle.

For example, ABC and BCD are two equal adjacent angles. Each equal to 44°.

ABC+BCD=44°+44°= 88°≠ 90°
