Write a definition of a right angle as a biconditional?

Question

i don't understand how to do this :/

Answer 1

A biconditional is a situation where one statement follows the logic of another.  For example, if P is true then Q is true and if Q is true then P is also true.

The biconditional definition of a right angle would be something like:

1. Given angle 1 and 2 equal.

2. Angle 1 is 90 degrees

3. Then Angle 2 is also 90 degrees

4. Therefore definition of right angles states both are right angles
