The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
How do you find exterior and interior anles on a triangle?
Use a protractor and you'll find that the 3 interior angles add up to 180 degrees and that the 3 exterior angles add up to 360 degrees
How do you use the exterior angles of a triangle to find interior angle measurements?
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
Can you find the exterior angle before the interior angle?
No, you cannot find the exterior angle before the interior because the interior angles can vary in many ways.

Exterior angle of a triangle?
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

What is The sum of the exterior angles of a docegon?
I think its this.... Find the interior. Then do 180 - the interior. That is the exterior. * * * * * The correct answer is that the sum of the exterior angles of any polygon is always 360 degrees.
If the internal angles of a triangle are in a ratio 3 5 7. Find the degree measures of the angles. Also find the measure of its greatest exterior angle?
Its interior angles are 36, 60 and 84 degrees respectively with its greatest exterior angle being 144 degrees.
A figure has 3 sides What is the sum of its exterior angles?
360A triangle is a polygon with three sides and three angles. The sum of the interior angles of a polygon equals 180(n - 2), where n is the number of sides.180(3 - 2) = 180°Assuming all the angles in the triangle are congruent, find the measure of one interior angle.180° ÷ 3 = 60°If an interior angle equals 60°, then its corresponding exterior angle will equal 120° because the angles are supplementary (their sum is 180°).120° × 3 = 360°Therefore, the sum of the exterior angles of a triangle is 360°.study island

Find x with 106 degree and 136 degree points in triangle?
It is not possible to answer the question without more information. Clearly, the two given angles cannot both be interior angles since were that the case, the triangle would have to be non-planar and then there is no information on the curvature of the space in which the triangle is. The angles could be one interior and one exterior or both exterior but there is no indication as to which is which. Finally, and most important, there is no information on what x is meant to be.
