Geometry Definition

What are two undefined terms that are useful for defining a segment?

• angle, line

• line, point

• point, ray

• ray, distance

Which is an undefined term that is useful for defining an angle?

• circle

• distance

• point

• ray

Which is an undefined term that is useful for defining a circle?

• angle

• distance

• line

• segment

Which best completes the definition below?

parallel lines: two or more lines on a plane that __________________

• have one point of intersection

• have no points of intersection

• are horizontal

• are vertical

Which best completes the definition below?

perpendicular lines: two lines whose intersection forms ____________

• acute angles

• complementary angles

• four angles

• right angles

What is described below?

all the points of a plane located a given distance from a given point

• circle

• line

• ray

• segment

What is described below?

all the points on a line located between points A and B, including points A and B

• ray AB

• segment AB

• a line that is parallel to line AB

• a line that intersects line AB

A circle is a set of all the points in a plane that have the same distance.

What needs to be clarified in this definition of a circle?

• that the points of the circle are the same distance from a given point

• that the points of the circle are the same distance from each other

• that the points of the circle are the same distance from the origin

• that the distance must be a rational number

If the intersection of two lines forms four congruent right angles, the lines are said to be perpendicular.

What could be done to make this definition more concise yet still valid?

• remove "congruent right"

• remove either "congruent" or "right," but not both

• remove "four congruent right"

• change "four" to "two" and remove "right"

The set of all points on a line between two endpoints is called a line segment.

What should be clarified in this definition?

• that the two endpoints are included as part of the line segment

• that the two endpoints are not included as part of the line segment

• that the set of all such points on a circle is also called a line segment

• that the set of points cannot be called a line segment if the endpoints are farther than a certain distance apart
