In the picture, one angle is labeled 22° and lines S and T are parallel. Which other three angles will be 22° ? Separate each angle number with a comma.

If lines S and T are parallel, then the alternate interior angles will be congruent. Therefore, the other three angles that will also measure 22° are the angle opposite to the labeled 22° angle, the angle adjacent to the labeled 22° angle, and the angle adjacent to the angle opposite to the labeled 22° angle. These angles are:

Opposite angle: 22°
Adjacent angle 1: 22°
Adjacent angle 2: 22°

So, the three other angles that will be 22° are 22°, 22°, and 22°.
