The perimeter is just the length of the outer line of the triangle and is similar to calculate like the circumference of a circle. An obtuse triangle is one of the three kinds of triangles which are obtuse, acute and right. An obtuse triangle is a one with an obtuse angle (angle > 90°). The given below is the Perimeter of Obtuse Triangle Formula for calculating the perimeter. As per the formula just substitute the lengths and add them to get the result.

Where,

P = Perimeter

A = Side A

B = Side B

C = Side C

A triangle must be either obtuse, acute or right-angled, which depends upon the angle formed within it. This is a simple and useful Perimeter of obtuse triangle formula to do the obtuse triangle calculations on your own by using the basic addition operation.
