Exterior Angles of Triangle - Definition, Formula, Properties
The exterior angle of a triangle is the angle that is formed with one side and the adjacent extended side of a triangle. There are 3 exterior angles in a triangle and the sum of the exterior angles of a triangle is always equal to 360°.
Exterior Angle Theorem - Math is Fun
Exterior Angle Theorem. The exterior angle d of a triangle: equals the angles a plus b. is greater than angle a, and. is greater than angle b. Example: The exterior angle is 35° + 62° = 97°. And 97° > 35°. And 97° > 62°.

2024年7月30日 · 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.
