Angles - Complementary, Supplementary, Adjacent, Vertical

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

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

Adjacent angles are angles that have a common vertex and a common side, and do not overlap.

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

The complementary angle measures 56° (90° - 34°).

The other angle measures 108° (180° - 72°).

The sum of the measures of two adjacent angles can be any value, depending on their individual measures.

To find the value of x, set up an equation based on the relationships between the angles (complementary, supplementary, etc.) and solve for x.

Vertical angles are equal in measure.

The other angle measures 135° (180° - 45°).
