Identify the Triangle from side lengths
All sides are equal in length
Equilateral Triangle
If all angles are equal, the triangle is
Equilateral
A triangle with equal angles and equal side lengths
Equilateral triangle
All sides are different lengths
Scalene Triangle
A triangle with one angle that is greater than 90 degrees and has two other angles less than 90 degrees.
Obtuse Triangle
A triangle that has all angles less than 90 degrees and no equal side lengths
Acute Scalene Triangle
Two legs are the same length
Isosceles Triangle

What is the difference between an obtuse scalene triangle and an acute scalene triangle?
Acute scalene has all angles < 90 degrees and no equal sides. Obtuse scalene has one angle > 90 degrees and no equal sides.
