Vocabulary congruent vertical angles adjacent angles complementary angles supplementary angles

Congruent angles have the same measure. Vertical angles are formed opposite each other when two lines intersect. Vertical angles have the same measure, so they are always congruent. MRP and NRQ are vertical angles. MRN and PRQ are vertical angles

Adjacent angles are side by side and have a common vertex and ray Adjacent angles are side by side and have a common vertex and ray. Adjacent angles may or may not be congruent. MRN and NRQ are adjacent angles. They share vertex R and RN. NRQ and QRP are adjacent angles. They share vertex R and RQ.

Complementary angles are two angles whose measures have a sum of 90°. 65° + 25° = 90° LMN and NMP are complementary.

Supplementary angles are two angles whose measures have a sum of 180°. 65° + 115° = 180° GHK and KHJ are supplementary.

Transversal Line When two parallel lines are cut by a third line, the third line is called the transversal.

Identify the type of each angle pair shown. 5 6 5 and 6 are opposite each other and are formed by two intersecting lines. They are vertical angles.
