What is a conclusion about the exterior angle of a triangle
Answers
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see Triangle external angle theorem. If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles
Answer:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles.
Step-by-step explanation:
When a side of a triangle the angle so formed is called as exterior angle of the triangle. Needless to say the sum of exterior angle and its adjacent angle are supplementary.
Every triangle thus has three exterior angles. Sum of the three exterior angles of a triangle is 360° since 1) the sum of interior angles of the triangle is 180° and 2) the sum of exterior angle and corresponding interior angle is 180°.
