Which lines are parallel in the square pyramid?

select each correct answer.

bc←→ and de←→

cd←→ and be←→

ad←→ and bc←→

ab←→ and ad←→

A square pyramid is a pyramid with a square base. In this problem, this base is formed by the points B, C, D and E as illustrated in the Figure above. So, the correct answers are:

First. (BC←→ and DE←→)

This is indicated in Figure 1. As you can see, the red lines are parallel, that is:

Recall that two lines are parallel if they are always the same distant apart in which case they are equidistant, that is, they never meet.

Second. (CD←→ and BE←→)

This is indicated in Figure 2. As you can see, the green lines are parallel, that is:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
