there is the Equilateral Triangle which all sides are equal.
there is the Isosceles Triangle where only two sides are equal.
there is the Scalene Triangle where no sides are equal.

Triangles can be classified by one of two different criteria. One is by the number of equal sides they have, in that sense, they can be classified as scalene, isosceles and equilateral. Other is the types of angles they posses, in which case they can be classified as either acute, right or obtuse triangles.
Equilateral triangle, Iscocolese triangle, Right angle triangle, And also toblerone but that's kind of a triangular prism :)
Many different types, but mostly equilateral triangles.
All right angle triangles
you can make 76 different triangles on a 3x3 grid
One way is they both are triangles and have 3 sides.
no
Many different types, but mostly equilateral triangles.
depends on what size triangles and what kind of triangles?
They can be any kind of triangles.
a pyramid can use any triangles possible.
Right-Angle triangles
scalene triangles
All right angle triangles
size
None because all triangles have 3 sides
You would get two scalene triangles.

There are 3 triangles in a pentagon
