Basic Constructions in Geometry

A specific location in space is called a...

• line

• point

• line segment

• ray

What kind of intersecting lines are these?

• Parallel Lines

• Perpendicular Lines

• Right Lines

• Scalene Lines

To construct an equilateral triangle, all you need is a compass and a straightedge.

• True

• False

A line, segment, or ray that passes through the midpoint of a side that is creates a 90 degree angle with that side.

• Perpendicular bisector

• Angle bisector

• Median

• Altitude

Based on the construction, which conclusion is not always true?

A flat surface is called a...

• plane

• line

• point

• ray

Which image shows the construction of a perpendicular bisector?

Which construction illustrates “copy an angle”?

• 
• 
• 
• 

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
