Two angles have the same measure. The angles are also supplementary. Are the angles acute, right, or obtuse? How do you know?

They are 90 degrees because supplementary means that it equals 180 and 90+90=180

Both the angles are right angles

Step-by-step explanation:

They both are right angles because supplementary angles are 2 angles whose sum = 180 degrees

Because they both have the same measure you can write an equation such as:

2x = 180.

When you divide 2 on both sides you end up with x = 90 degrees

90 degree angles are right angles.
