A step by step review of each question

Name the four undefined terms.

POINT

LINE

PLANE

SET

The set of points all of which lie on a line.

A LINE SEGMENT

A polygon that has exactly three sides.A TRIANGLE

Any line, line segment, or ray that intersects a line segment at its midpoint.

A BISECTOR

Two rays on the same line that share a common endpoint and have

no other points in common.Opposite Rays

• A triangle that has two congruent sides.ISOSCELES

• Angles that have the same measure.CONGRUENT

• A triangle that has no congruent sides.SCALENE

• Two lines that intersect to form right angles.PERPENDICULAR

• A set of three or more points all of which lie on the same straight line.

COLLINEAR

Explain why a line segment can have only one midpoint but can have many different bisectors.

A midpoint is the point in the exact middle of a line segment, so there can be only one point at that position. A bisector is a line that goes through that point and could go through at many different angles.
