Exterior angle property of a triangle?
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
An exterior angle at the base of an isosceles triangle measures 110 find the measure of the vertex angle?
40
An exterior angle at the base of an isosceles triangle measures 130 find the measure of the vertex angle?
80 degrees.
What is the relationship between interior and exterior angles in triangles?
An interior angle of a triangle is the angle between two edges, measured inside the triangle. An exterior angle is formed by extending one of the edges outside the triangle, and measuring between that extension and the adjacent original side of the triangle. The sum of the interior angle and exterior angle at any given corner is always 1800 (which is Pi radians).
What is the largest exterior angle that any regular polygon can have?
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
How do you find a missing exterior angle of a triangle?
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is a Exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
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.

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.

Can the exterior angle of triangle be straight angle?
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
An exterior angle at the base of an isosceles triangle measures 110 find the measure of the vertex angle?
40
Is an exterior angle of a triangle always acute?
No :) Because one angle of the triangle is always acute and so the exterior has to be obtuse.
