Question

Write converse, inverse and contrapositive of the following conditional statement:
If an angle is a right angle then its measure is ${90}^{\circ }$.

Answer 1

Given: If an angle is a right angle then its measure is ${90}^0$

Converse: If the measure of an angle is ${90}^0$ then it is a right angle.

Inverse: If an angle is not a right angle then its measure is not ${90}^0$.

Contrapositive: If the measure of the angle is not ${90}^0$ then it is not a right angle.
