These are the different types of triangles and how to classify them:
Identify triangles by the length of the triangles:
When a triangle has 2 equal length sides, it is called an idosceles triangle. Like the picture show above, the ac side has the same length ad cb so it has the diagonal mark — and resembles an isosceles triangle
Equilateral triangles are triangles that has equal lenthgs of all 3 sides and equal angle for all three corners just like the picture how above. A triangle only has 180 degrees altogether for 3 corners, so an equilateral would always have 60 degrees for each corner since every single corner has to have the same angle and same length. Hehe. Logik.
A scalene triangle has no equal length of sides and no equal angles. So the triangle would look quite odd in different shapes.
Here’s a small review of all triangles that can be identified and classified by the lengths of their sides
Identify triangles by their angles:
Right triangles are triangles tat only has 1 right angle (s).
Obtuse triangle are triangles that has only 1 obtuse angle that means 1 angle more than 90 degrees.
To identify an acute triangles you have to be able to check if the angles are smaller than 90 degrees and all angles as to be less than it.
