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.

Interior Angles Theorem If two lines are intersected by a transversal and same-side interior angles are supplementary, then the lines are parallel Theorem If two intersecting lines form a linear pair of congruent angles, then the lines are perpendicular Theorem If two lines are perpendicular to the same transversal, then they are parallel
The most well-known result about triangles is now in our grasp, that the interior angles sum to a straight edge. Euclid words this slightly differently. Theorem 2.7 (I.32). If one side of a triangle is extended, the exterior angle is congruent to the sum of the opposite interior angles. This is not a numerical sum, though for familiarity’s ...
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.
14 cze 2023 · Angles that are found inside or within any geometric shape are called interior angles. They are also sometimes called internal angles. A triangle has three interior angles. Similarly a quadrilateral such as a square, rectangle, parallelogram, kite, or a trapezoid has four interior angles.
10 wrz 2024 · Alternate Interior Angles. A line intersecting two parallel lines forms eight angles, as shown in Figure \( \PageIndex{ 12 } \). This line is called a transversal. There are four pairs of vertical angles and four pairs of corresponding angles, or angles in the same position relative to the transversal on each parallel line.
