4 What are the 4 kinds? I count 2 kinds: the base is a square, and the other 4 faces are all triangles.
All triangles have exactly three sides. If the number of sides were anything other than three there would not be a triangle - of any kind.
isolies
There are: Isoceles, Right, Scalene, and Equilateral.
orthocenter
They are classified as: scalene, obtuse, right angle. equilateral and isosceles

Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.

No. But all isosceles triangles and equilateral triangles are.
One pentagon and five triangles.
