Question

15. Is the statement below always, sometimes, or never true? Explain. "If two angles are right angles, they must be supplementary."

Answer 1

yes. the sum is 180

Explanation

Step 1

Two angles are called supplementary when their measures add up to 180 degrees.

then ,

if 2 angles are right angles

$\text{angle}_1=angle_2=90$$\text{angle}_1+angle_2=90+90=180$

so, angles are supplementary

because the sum is always 180 degrees
