Prove the following theorem indirectly. we will give you a start.

prove that a triangle cannot have two right angles.
a triangle cannot have two right angles. suppose a triangle had two right angles.

Step-by-step explanation:

Suppose a triangle had two right angles.

The sum of all angles of any triangle is 180°.

The measure of a right angle is 90°.

By difference, the measure of the other angle can be determined.

Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.

If the angle is 0°, there would only be two sides.

A triangle has three sides.

Therefore, a triangle can't have two right angles.
