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:

\overline{BC} \ is \ parallel \ to \ \overline{DE}


Recall that two lines are parallel if they are always the same distant apart in which case they are <em>equidistant, </em>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:

\overline{CD} \ is \ parallel \ to \ \overline{BE}

Answer:  The correct options are

(A) BC←→ ​and DE←→

(B) CD←→ and BE←→

Step-by-step explanation:  We are given to select each pair of sides that are parallel to each other in the square pyramid.

We know that

the base of a square pyramid is a square. And the opposite sides of a square are parallel to each other.

So, in the given square pyramid ABCDE, the base is a square BCDE.

Therefore, the pair of parallel sides are

BC and DE ;  CD and BE.

This implies that option (A) and (B) are correct.

Thus, the correct options are (A) and (B).

which three numbers make a right triangle the square root of 4 the square root of 5 the square root of 9 + square root of 6 the
statuscvo [17]
Please, group your sets of numbers, using {   }  notation or at least semicolons ( ; ).  Thanks.

Looking at what I think is your first set:   { sqrt(4), sqrt(5), sqrt(16) }

Square each of these and then subst. the results into the Pythagorean Theorem:

  { 4, 5, 16 }        Do 4 and 5 when added together result in 16?  NO.
Therefore,   { sqrt(4), sqrt(5), sqrt(16) }  does not produce a right triangle.

Your turn.  Pick out the next 3 numbers and test them using the Pyth. Thm.
