Acute triangle
In an acute triangle, all angles are less than right angles—each one is less than 90 degrees

Right triangle
a triangle with a right angle.

Obtuse triangles
The indicated angle is larger then 90 degrees.

Scalene triangle
A scalene triangle is a triangle that has three unequal sides.

Isosceles triangle
an isosceles triangle is a triangle that has two sides of equal length

Equilateral triangle
