Lines and angles. A line is an infinite number of points between two end points. Where two lines meet or cross, they form an angle. An angle is an amount of rotation. It is measured in degrees. Types of angles. Name of angle. Example.
Same-side Interior Angles Theorem If two parallel lines are intersected by a transversal, then same-side interior angles are supplementary. Converse of Alternate Interior Angles Theorem If two lines are intersected by a transversal and alternate interior angles are equal in measure, then the lines are parallel Converse of Alternate Exterior Angles

Angle-Side-Angle (ASA) Congruence Postulate: If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. Theorems 4.1 Triangle Sum Theorem: The sum of the measures of the interior angles of a triangle is 180 o.
The next result is one of the most important in Euclidean geometry, in that it describes how to create a parallel line through a given point. Theorem 2.3 (I.16 Exterior Angle Theorem). If one side of a triangle is extended, then the exterior angle is larger than either of the opposite interior angles.
The angles that lie inside a shape, generally, a polygon, are said to be interior angles, or the angles that lie in the area enclosed between two parallel lines that are intersected by a transversal are also called interior angles. Learn more about interior angles in this article.
