Answer 1

ok what's the problem dearest girl?

Answer 2

@IMStuck Bonjour dear! *It's above :)

Answer 3

Got it! What do you think it is?

Answer 4

Its faces are all the same exact size triangles. Its base is a square, but the base is not a face.

Answer 5

It is regular, let me just throw that out there.

Answer 6

:( I thought it was C.

Answer 7

And a straight line drawn from the tippy top to the base will meet in perfect right angles. What do you think it is now?

Answer 8

no it's definitely regular. So A or B. Which one?

Answer 9

A.

Answer 10

While that is a true fact, it is not one used to classify polyhedrons as regular or nonregular. The faces are used for that purpose. So it's B.

Answer 11

Regular Polyhedron

Regular Polyhedron
A polyhedron whose faces are identical regular polygons.

There are five convex regular polyhedra, known as the Platonic Solids.

There are also four regular "star polyhedra", known as Kepler-Poinsot solids.

This is a regular polyhedron (an Octahedron).

Answer 12

Look at the first fact about regular polyhedrons.

Answer 13

The faces are identical regular polygons. Hence the name "regular polyhedron". A solid made up of regular polygons.

Answer 14

Ignore the rest of that jibberish. Just look at the first fact.

Answer 15

If the shape would have pasted along with the explanation, it would all make sense. But it didn't copy, so I'm sure it's nonsense.
