Based on the interior angles, triangles are classified into three types, they are: Acute angle triangle. Obtuse angle triangle . Right angle triangle. Acute Angle Triangle. A triangle where all three interior angles are less than 90 degrees is called an acute-angled triangle. Obtuse Angle Triangle WebThere are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length. A triangle’s name also depends on the size of its inside angles: acute if all angles are less than 90°, right-angled if one angle is 90°, or obtuse if one angle is more than 90°. pelvic gas pain in men
