Your st 1 Geometry Test 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 L I N E S E G M E N T 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.
