Exterior angles of a triangles
WebAn angle formed between a side of the triangle and an adjacent side extending outward is called an exterior angle.The exterior angle of a triangle is equal to the sum of the two … WebAn exterior angle is when a line is drawn outside of the triangle, extending the angle. The exterior angle is ∠ ACD. All the angles inside the triangle are interior angles. A little side note: the exterior angle and the adjacent interior angle (the one connected to it) always add up to 180° because together they form a line.
