**Interior and Exterior angles? Yahoo Answers**

Let the exterior angles of a triangle be rearranged so that they have the same vertex as shown above. Let us now consider the external angle sum of a rectangle. Let the exterior angles of a rectangle be rearranged so that they have the same vertex as shown above.... The sum of exterior angles - watch out! In most geometry textbooks they say flatly that the exterior angles of a polygon add to 360° This is only true if: You take only one per vertex, and Take all the angles that point in the same direction around the polygon. But in many cases they fail to state these conditions. In the figure at the top of the page, check the "Both" checkbox. You will see

**Exterior Angle of a Triangle Passy's World of Mathematics**

And our little drawing shows that the exterior angle in question is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the angle in the bottom right corner to make a 180 0 angle.... Question from gn, a parent: The sum of the exterior angles of any convex polygon is 360 degrees. That means that if you have n sides, then each exterior angle of a regular polygon is 360/n. If you can find out how the exterior angle is related to the interior angle, you can finish the solution. Stephen La Rocque.> Hi, While it could be done, with algebra, using interior angle sums etc. I

**Interior and Exterior angles? Yahoo Answers**

The exterior angle theorem states that the exterior angle formed when you extend the side of a triangle is equal to the sum of its non-adjacent angles. Remember, our non-adjacent angles are those how to get rid of a competitive friend We already know that the sum of the interior angles of a triangle add up to 180 degrees. So if the measure of this angle is a, the measure of this angle over here is b, and the measure of this angle is c, we know that a plus b plus c is equal …

Exterior Angle The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and Exterior Angle … how to get grease out of upholstery fabric The sum of exterior angles - watch out!

## How To Find Out The Exterioir Sum

An exterior angle is equal to the sum of the non-adjacent interior angles. In our triangle, we can use A and B to figure out D . If we know A is 65 and B is 70, we can just add them to get 135

- 9/11/2008 · Best Answer: The sum of the interior angles for any convex polygon is given by (n - 2)*180, where n is the number of sides. If the polygon is regular, then every interior angle is identical, so just take (n - 2)180/n and that's one of them.

- And our little drawing shows that the exterior angle in question is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the angle in the bottom right corner to make a 180 0 angle.
