What is a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.

(a)  

Three non-collinear points (points not on a single line). A line and a point not on that line. Two distinct but intersecting lines.

(a)  

A point B that lies on the line connecting two points A and C and has one of the two points on each side of it.

(a)  

What is a part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.

(a)  

What is an infinitely long object with no width, depth, or curvature

(a)  

What is a line, ray, or segment that cuts another line segment at the center dividing the line into two equal halves

(a)  

What is three or more points that lie on a single straight line.

(a)  

the line or line segment that divides the angle into two equal parts

A statement, also known as an axiom, which is taken to be true without proof.

(a)  

less than 90 degrees

(a)  

any angle greater then 90 degrees but less than 180

(a)  

What is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment
