Angle Relationships Basic

Two angles that have the same measure.

• congruent
• complimentary
• adjacent
• transversal

The line that cuts through two parallel lines. 

• adjacent
• transversal
• parallel
• congruent

Two angles that lie on the same side of the transversal, in relative positions; congruent.

• vertical
• alternate interior
• corresponding
• supplementary

Two angles that are next to each other. 

• congruent
• supplementary
• vertical
• adjacent

Two angles that make a right angle.

• complementary
• supplementary
• corresponding
• adjacent

Two or more angles that make a straight line. 

• complementary
• supplementary
• alternate interior
• adjacent

Two angles inside the parallel lines but on opposite sides of the transversal. 

• alternate exterior
