any other exterior angle of the triangle * * * * * No. The sum of the two opposite interior angles.
Interior angle+exterior angle = 180 degrees
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
The sum of the exterior angles of any polygon is 360 degrees.
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
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
exterior angle theorem
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
The sum of the interior angles of any triangle is 180 degrees.
In any triangle exterior angle plus interior angles = 180 degrees
The sum of the angles should equal 180
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.
