Question

<1 and <2 are supplementary and <1 = <2. Which one of these students will always be true.

Answer 1

Two angles are supplementary if their sum is 180 degrees. Since angles 1 and 2 are supplementary, then

angle 1 + angle 2 = 180

If angle 1 = angle 2, then,

If angle 1 = angle 2 = 180/2 = 90

90 degrees is a right angle

Thus,

angle 1 and angle 2 are right angles
