Supplementary angles are two angles whose measures sum to 180 degrees. The document provides examples of supplementary angle pairs and their measures, including the angles BEN and TEN which have measures of 120 and 60 degrees respectively, summing to 180 degrees. It also includes a table asking the reader to find the measure of the missing angle for various given supplementary angle pairs.

3. Condition Acute Right Obtuse
1. An angle whose measure is greater
than 900 but less than 1800.
2. An angle whose measure is greater
than 00 but less than 900.
3. An angle whose measure is 90.990.
4. The angle is 159.50, what is its
classification.
5. This angle measures 900.

4. Supplementary
angles are two angles
whose measures have
a sum of 180°.

5. Consider BEN and TEN
m BEN = 1200
m TEN = 600
m BEN + m TEN
= 1200 + 600
= 1800
m BEN + m TEN = 1800
BEN and TEN are
supplementary angles.
