Question

Figure LMNO is a parallelogram.

A parallelogram has points on each corner. The points are M, N, O, L going from the top left, clockwise.
Angles L and M are supplementary. What is the sum of their measures?

The sum of the measures of angles L and M is °.

Answer 1

Answer: 180 degrees

Explanation:

Supplementary angles add up to 180 degrees.

So and L and M add up to 180 degrees.

Answer 2

Since LMNO is a parallelogram, opposite angles are congruent, which means that angle L is congruent to angle N and angle M is congruent to angle O.

Since angles L and M are adjacent angles in a parallelogram, they are supplementary, which means that their sum is 180 degrees. Therefore, the sum of the measures of angles L and M is:

L + M = 180 degrees.
