Consider the following conditional statement. Rewrite the statement in if-then form, and then write the converse, inverse Converse contrapositive, and biconditional.

Right angles are 90°

If-then:

Converse:

Inverse:

Contrapositve:

Biconditional:

Given: Right angles are 90 degrees.

if-then: If it is a right angle, then it's 90 degrees.

Converse: If the angle is 90 degrees, then it's a right angle.

Inverse: If it is not a right angle, then it's not 90 degrees.

Contrapositive: If the angle isn't 90 degrees, then it's not a right angle.

Bi-conditional: It is a right angle if and only if it's 90 degrees.
