WebOct 17, 2024 · Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles. WebExterior angle definition, an angle formed outside parallel lines by a third line that intersects them. See more.
WebAlternate exterior angles are a pair of angles formed on the outside of two lines that are crossed by a third line. The alternate angles are located on opposite sides of the transverse line. Depending on the nature of the … WebA transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry. A transversal intersection with two lines produces various types of angles in pairs, such as consecutive interior angles, corresponding angles and alternate angles. A transversal produces 8 angles and this can be observed ...
WebAn exterior angle can be calculated if the number of sides of a regular polygon is known by using the following formula: Exterior Angle = 360º/n, where 'n' is the number of sides of the polygon.
