GEOMETRY LINE CONSTRUCTIONS

Which one is the correct construction for a perpendicular bisector?

• 1

• 2

• 3

• 4

What does the word BISECT mean?

• To cut something into more than five pieces.
• It is a plane with two sets of wings.
• A shape that has three sides. 
• To cut something into two congruent pieces or in half.

To construct an equilateral triangle, all you need is something to write with and a ruler.

• True
• False

Which of the following constructions is illustrated?

• An angle is congruent to a given angle

• The bisector of a given angle

• equilateral triangle

• The perpendicular bisector of a given segment.

When copying line segment AB using a straight edge and a compass, the compass should be used to:

• Draw an arc above point A

• Measure the length of segment AB

• Draw an arc between point A and point B

• Measure half the length of line segment AB

What was duplicated?

• line

• line segment

• ray

• angle

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°
