Exterior angle of a triangle?

Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

How do you find a mesaure of an exterior angle on a triangle?

To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.


In ade if angle gea is an exterior angle what are the remote interior angles?

In triangle ADE, if angle GEA is an exterior angle, the remote interior angles are angles DAE and DEA. These are the angles inside the triangle that are not adjacent to the exterior angle GEA. According to the Exterior Angle Theorem, the measure of angle GEA is equal to the sum of the measures of angles DAE and DEA.
