The word geometry comes from the Greek words geo and metron. What do they mean?

• Earth and angle

• Measure and line

• Earth and measure

• Point and space

Multiple Choice

Points, Lines, and Planes

A point is described as:

• A part of a line with one endpoint

• An exact location in space with no dimension

• A straight path extending in two directions

• A closed curve on a plane

Multiple Choice

Lines that never intersect and remain the same distance apart are called:

• Intersecting lines

• Parallel lines

• Perpendicular lines

• Line segments

Multiple Choice

A flat surface that extends indefinitely in all directions is called a:

• Line

• Plane

• Ray

• Circle

Multiple Choice

A line segment is:

• A straight path with no beginning and no end

• A part of a line that has two endpoints

• A part of a line that has only one endpoint

• A flat surface that extends in all directions

Multiple Choice

Angles

An angle is made up of:

• Two rays with the same endpoint

• Two lines with no endpoints

• Two planes intersecting

• A straight path of points

Multiple Choice

Which of the following describes a reflex angle?

• Measures exactly 90°

• Measures less than 90°

• Measures greater than 180° but less than 360°

• Measures 360°

Multiple Choice

If two angles add up to 180°, they are called:

• Complementary

• Supplementary

• Perpendicular

• Straight

Multiple Choice

Which of the following real-life examples best illustrates perpendicular lines?

• Edges of a ruler

• Crossroads at a right angle

• A ladder leaning on a wall

• Spokes of a bicycle wheel
