Angle pairs

Supplementary angles are two angles whose measures add up to 180 degrees.

Complementary angles are two angles whose measures add up to 90 degrees.

Angle TRS measures 115 degrees.

An angle bisector is a line or ray that divides an angle into two equal parts.

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

A linear pair of angles are two adjacent angles that form a straight line, adding up to 180 degrees.

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Angle B measures 60 degrees.

Adjacent angles share a common side and vertex but do not overlap.
