Series: Lines and Angles
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 interior angle, and alternate exterior angle. Show Less
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 then they are called a linear pair. Show Less
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.
