What is the relationship between an exterior angle of a triangle and its two remote interior angles?
A. Exterior angle + remote interior angle + remote interior angle = 180°
B. Exterior angle = (remote interior angle + remote interior angle)
C. Exterior angle + remote interior angle + remote interior angle = 90°
D. Exterior angle = (remote interior angle – remote interior angle)

A.

The measure of an exterior angle = the sum of the measures of the two remote interior angles.

anonymous · Answer

the sum of the two remote interior angles in a triangle adds up to the exterior angle of the other angle . this is because the sum of the angle in the triangle is 180  and a line forms an angle of 180 degree. there fore , the sum of the two angle must complete the other angle to 180, and the exterior angle of that angle also add up to 180 therefore, the sum of two interor angle of a triangle must equal the measure of the exterior angle of the third angle.
