An obtuse triangle is a triangle which has an obtuse angle. An obtuse triangle will have only one obtuse angle (more than 90°) and two acute angles. It can be dissected into seven acute triangles and not more than that. Use our online Perimeter of obtuse triangle calculator to find the perimeter of an obtuse triangle. Since, the perimeter of a triangle is the sum of measurement of all of its sides so just enter the sides and know the perimeter.
Calculate the perimeter of obtuse triangle with its length measurements of three sides be 50 cm, 35 cm and 60 cm.
P = 50 + 35 + 60
= 145 cm
