Equilateral triangles have 3 sides all of the same lengths and the three angles are equal (60°).
Isoceles triangles have two sides of equal length with both of those side angles being equal while the other is different.
Scalane triangles have all sides of different lengths and different angles.
Right angled triangles have one angle of 90° and the other two will total 90°.

Are there triangles with 4 sides?
No. Triangles all have three sides.
What is the reason for using all triangles?
Because all other polygons are made from triangles as for example an 8 sided octagon has 6 triangles within it or a 6 sided hexagon has 4 triangles within it.
What has 4 faces all of which are equilateral triangles?
Tetrahedron
How many triangles are in a 4-sided polygon?
You could draw four different triangles in a 4-sided polygon, but two are enough to define the polygon.

What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
What are the 4 different triangles called?
isosceles, scalene , equilateral, right angle triangle
