Question

use the pyramid to complete parts (a) through (f) below.
c. what is the intersection of bc and cd?
a. point c
b. ∅
c. plane abc
d. point d
d. which pair of lines are skew lines?
a. ad and bc
b. ab and cd
c. be and ae
d. cd and be
e. find a pair of distinct parallel lines. choose the correct answer below.

Explanation:

Step1: Recall line - intersection concept

Two lines that share a common point intersect at that point. Lines BC and CD share point C.

Step2: Analyze skew - lines concept

Skew lines are non - parallel and non - intersecting lines in 3 - D space. In a pyramid, CD and BE are non - parallel and do not intersect as they lie in different non - overlapping planes.

Answer:

c. A. Point C
d. D. CD and BE
