WebAn angle is the space between two intersecting lines or shapes and it is usually measured in degrees. Now lets consider interior and exterior angles. Any angle that is on the inside of a shape is called an interior angle. Any angle that is on the outside of a shape is called an exterior angle.

Web2 feb. 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle.
WebAlternate exterior angles are congruent (every other angle outside the parallel lines). Non-congruent special angles are supplementary. Given two (interior) angles in a triangle, their sum must be less than 180 degrees. If the sum were equal to 180, then the triangle would have two parallel sides, and thus no third vertex. lower back hurts when i breathe in deeplyWebAn angle is the space between two intersecting lines or shapes and it is usually measured in degrees.
