what is exterior angle:?
An exterior angle of a triangle is the angle formed by extending one of the sides of the triangle thoruogh a vertex
exterior angle + interior angle = 180 degrees
how many exterior angles ,does a triangle have?
=>we know that it has three vertices
=>vertex is formed by joining two lines
=>so exterior angle in one vertex = 1*2 = 2 angles
so in the same way exterior angle in 3 vertices = 3*2
= 6 exterior angles

Every triangle has 6 exterior angles, two at each vertex. Notice that the "outside" angles that are "vertical" to the angles inside the triangle are NOT called exterior angles of a triangle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
