An angle is formed from the intersection of 2 lines at 1 point, a ray is part of one or 2 of those lines with 1 endpoint, and the angle is defined from the undefined term lines; undefined terms are also known as "primitive terms"; a point acts for a location, and an angle is determined by 3 points, with the point in the midle representing the vertex, Thus the answer is the 3rd one (point).
