Exterior Angle Theorem An exterior angle of a triangle is equal in measure to the sum of the measures of its two remote interior angles. remote interior angles Exterior angle Exterior Angle Theorem The measure of an exterior angle in a triangle is the sum of the measures of the interior oppo...
Geometry is a branch of mathematics that deals with shapes, sizes, angles, and positions. One concept of geometry involves the sum of exterior angles in a triangle. A triangle is a three-sided shape composed of three straight line segments connecting at
The same works for a special type of rectangle – a square – here, the angle and its complementary angle are even equal to each other (45°). Complementary angles in a right triangle Take a look at a right triangle's height – did you notice that altitude, h꜀, from the right ...
