A right triangle is 90 degrees

In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

a obtuse triangle is any angle from 91 to 179 degrees

an acute triangle is any angle from 1 to 89 degrees
