Angles on Lines and Figures Vocabulary 5.02

90ᵒ Angle Terms right perpendicular Complementary Also called a ________________ angle Two lines that intersect to form 90ᵒ angles are called __________________________ lines. Example: Symbol: ____________________ angles: angles that together create a right angle and add up to 90ᵒ perpendicular Complementary

180ᵒ Angle Terms straight straight Supplementary Also called a _________________ angle A 180ᵒ angle forms a __________________ line. Example: _________________________ angles: angles that together create a straight line and add up to 180ᵒ straight Supplementary

Parallel Lines and Transversals Lines that will never intersect because they are going the exact same direction Symbol: Transversal: A line that intersects a set of parallel lines

Vertical Angles directly across the vertex (diagonal to each other)

Adjacent Angles that share a common side (next to each other)

Corresponding Angles in the exact same position on each parallel line

Interior Angles in between the parallel lines or inside of the figure

Exterior Angles outside of the figure or not enclosed in the parallel lines

Consecutive Angles on the same side of the transversal

Alternate Angles on different sides of the transversal
