Question

If < D is a right angle and < E is a right angle, and you said that < D is congruent to < E, the reason would be ____.

Answer 1

Given: Angle D is a right angle and angle E is a right angle.

Required: To give the reason for

$\angle D\cong\angle E$

Explanation: Since a right angle has a measure of 90 degrees. Hence all right angles have equal values. Hence all the right angles are congruent.

$\angle D\cong\angle E\text{ \lparen All right angles are congruent\rparen}$

Final Answer: Option A is correct.
