In how many points do the rays intersect?

answer:

1 point

an angle is a shape, formed by two lines or rays diverging from one common point (the vertex). answer: assuming it's not a 0° angle nor an 180° angle, the rays intersect in c) 1 point.

step-by-step explanation:

dont know found it on google

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
