An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
the exterior angle theorem
Remote interior angles
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
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
They are all 60 degrees.
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
any other exterior angle of the triangle * * * * * No. The sum of the two opposite interior angles.
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
In any triangle exterior angle plus interior angles = 180 degrees
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.
