Type Of Triangles Youtube This elementary math video discusses the six different types of triangles: acute, obtuse, right, equilateral, isosceles, and scalene. for more free education. Solution: step 1: a right triangle has one angle = 90°. sum of known angles is 90° 35° = 125°. step 2: the sum of all the angles in any triangle is 180°. subtract sum of known angles from 180°. 180° − 125° = 55°. answer: the size of the third angle is 55°. The 6 main types of triangles: by side and by angle. triangles types are named and classified by their sides and by their angles. by angle: acute triangle — all angles are less than 90°. right triangle — has an angle that is exactly 90°. obtuse triangle — has one angle that is more than 90°. by side:. Acute isosceles triangle: a triangle in which all 3 angles are acute angles and 2 sides measure the same is called an acute isosceles triangle. right scalene triangle: a triangle in which any one of the angles is a right angle and all the 3 sides are unequal, is called a right scalene triangle. obtuse scalene triangle: a triangle with an obtuse.
