Angles Made by a Transversal

Angles Made by a Transversal

A line that intersects two or more lines at distinct points is called a transversal. When a transversal cuts two lines, 8 angles are formed. These angle have special names such as interior angle exterior angle, corresponding angle, alternate...Show More

Complementary Angles, Supplementary Angles, Linear Pairs

When the sum of the measures of two angles is 90°, the angles are called complementary angles. When the sum of the measures of two angles is 180°, the angles are called supplementary angles. When two angles are both adjacent and supplementary...Show More
Intersecting Lines and a Transversal

Intersecting Lines and a Transversal

Lines that intersect at a common point are called intersecting lines and the common point is called the point of intersection. A line that intersects two or more lines at distinct points is called a transversal.
