Question

Need answer ASAP! I only have two questions left!!!

What is the name of an interior angle of a triangle that shares a side and a vertex with an exterior angle of the triangle?

A) exterior angle
B) adjacent interior angle
C) remote interior angle
D) alternate interior angle

Answer 1

Answer: B) Adjacent interior angle

As the name implies, the angle is inside the triangle and it is adjacent (ie next to) the exterior angle. Contrast this with a remote interior angle, which is also inside the triangle, but it is not adjacent to the exterior angle in question. Alternate interior angles won't apply here because we don't have a set of parallel lines with a transversal cut.
