What is this?

• Compass

What do you call the common endpoint of two rays? 

• Angle

• Segment

• Ray

• Vertex 

What geometric construction is shown in the diagram below?

What type of construction is illustrated in the figure?

• The bisection of ∠D

• The bisection of segment BD

• An angle congruent to ∠D

• A line segment congruent to segment AB

Which type of construction can be accomplished by using the method shown?

• congruent segment

By using a compass, D and G were marked equidistant from Vertex E. The compass was then used to locate point F, distant from E, so that F is equidistant from D and G. For all constructions defined by the above steps, the measures of DEF and GEF

• are equal

• are NOT equal

• sum to 45°

• sum to 30°
