Question

Where does a point lie if it is on a segment whose endpoints are on the sides of the angle, but it is not an endpoint of the segment?

Answer 1

two angles that share a vertex and a side but no points in their interiors ... a point is in this if it does not lie on the angle itself and it lies on a segment with ... a measurable part of a line that consists of two points, called endpoints, and all of the ... an adjacent angle whose noncommon sides are opposite rays (supplementary).

I tried to find the answer for you, i hope this helps!!!
