Geometry - Unit 1 Review (Semester 1 Benchmark)

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

• have one point of intersection

• have no points of intersection

• are horizontal

• are vertical

perpendicular lines: two lines whose intersection forms ____________

• acute angles

• complementary angles

• four angles

• right angles

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

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

• circle

• line

• ray

• segment

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 AB

• a line that intersects 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

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

Which of the following could be proven from Figure 1?

• The sum of the measures of angles 2 and 3 is 180°.

• Angle 2 is congruent to angle 4.

• Neither choice A nor choice B.

• Both choice A and choice B.
