Unit 1 Review - Geometry

Clare used a compass to make a circle with a radius the same length as segment AB. She labeled the center C. Which statement is true?

• AB > CD

• AB = CD

• AB > CE

• AB = CE

How does the length of segment CE compare to the length of segment AD?

In the construction, A is the center of one circle, and B is the center of the other. Identify ALL segments that have the same length as segment AB.

• segment AC

• segment AE

• segment BC

• segment CD

• segment DE

This diagram is a straightedge and compass construction. A is the center of one circle, and B is the center of the other. Select all the true statements.

• Line CD is perpendicular to segment AB

• Point M is the midpoint of segment AB

• The length AB is equal to the length CD

• Segment AM is perpendicular to the segment BM

• CB + BD > CD

Line segment CD is the perpendicular bisector of line segment AB. Is line segment AB the perpendicular bisector of line segment CD? How do you know?

A, B, and C are the centers of the three circles. Which line segment is congruent to HF?

• AB

• CD

• DF

• CB

This diagram is a straightedge and compass construction. Which triangle is equilateral? Explain how you know.

Which of these statements is true?

• All rectangles are regular polygons.

• All squares are regular polygons.

• All rhombi are regular polygons.

• All parallelograms are regular polygons.

Which digital construction tool would help you determine whether point C or point D is the midpoint of segment AB?

• Angle bisector

• Perpendicular bisector

• Perpendicular line

• Parallel line

Which construction could be used to construct an isosceles triangle ABC given line segment AB?

• Mark a third point C not on segment A B . Draw segments A C and B C .

• Label a point C on segment A B and construct a line perpendicular to A B through point C . Draw segments A C and B C .

• Construct the perpendicular bisector of segment A B . Mark the intersection of this line and A B and label it C . Draw segments A C and B C .

• Construct the perpendicular bisector of segment A B . Mark any point C on the perpendicular bisector except where it intersects A B . Draw segments A C and B C .
