Question 5

Which statements are true? Select three options.

Revolt · Accepted Answer

[image 1] and [image 2] are parallel.; [image 1] and [image 2] are perpendicular.; lies in plane X.

Question 6

The undefined terms line and plane are needed to precisely define which mathematical term?

Revolt · Accepted Answer

parallel lines

Question 7

Which statements are true regarding the diagram? Check all that apply.

Revolt · Accepted Answer

is contained on line m.; Ray AD is the same as ray AC.; ∠ECB is created from [image 1] and [image 2] .

Question 8

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?

Revolt · Accepted Answer

Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

Question 9

What did you include in your response? Check all that apply.

Revolt · Accepted Answer

Parallel lines do not intersect.; Parallel lines must be coplanar.; Perpendicular lines intersect at one point.; Perpendicular lines intersect so plane is not required in the definition.

Question 10

Which geometric figures are drawn on the diagram? Check all that apply.
