What does the term "collinear points" refer to?

• A set of points that lie on the same line

• Points that form a triangle

• Points that are in different planes

• A set of points that form a circle

What does "coplanar" mean in geometry?

• Points, lines, or segments that lie on the same plane

• Points that lie on the same line

• Lines that intersect at a point

• Segments that are parallel

What is a "line segment"?

• Part of a line with two endpoints

• A line that extends infinitely in both directions

• A curve with no endpoints

• A point with no dimensions

What are opposite rays?

• Two rays that share an endpoint and extend in opposite directions to form a line

• Two rays that never meet

• Two rays that form a right angle

• Two rays that are parallel

What is a midpoint?

• A point that divides a segment into two congruent segments, halfway between the endpoints

• A point that is at the end of a segment

• A point that is outside the segment

• A point that divides a segment into three equal parts

What is the midpoint formula?

• M(x, y) = (x_1 + x_2/2, y_1 + y_2/2)

• M(x, y) = (x_1 - x_2/2, y_1 - y_2/2)

• M(x, y) = (x_1 * x_2/2, y_1 * y_2/2)

• M(x, y) = (x_1 / x_2, y_1 / y_2)

What is a segment bisector?

• A point, line, ray, or segment that divides a segment into two congruent segments

• A line that divides a segment into three parts

• A ray that extends infinitely

• A point that is at the midpoint of a segment

What is an obtuse angle?

• An angle that measures exactly 90 degrees

• An angle that measures less than 90 degrees

• An angle that measures greater than 90 degrees and less than 180 degrees

• A ray that divides an angle into two congruent angles

What is an acute angle?

• An angle that measures exactly 90 degrees

• An angle that measures less than 90 degrees

• An angle that measures greater than 90 degrees and less than 180 degrees

• A ray that divides an angle into two congruent angles

What is a right angle?

• An angle that measures exactly 90 degrees

• An angle that measures less than 90 degrees

• An angle that measures greater than 90 degrees and less than 180 degrees

• A ray that divides an angle into two congruent angles
