Do all triangles have a right angle

WebThe Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C).

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°. WebJan 20, 2024 · All triangles have interior angles adding to 180°. When one of those interior angles measures 90°, it is a right angle and the triangle is a right triangle.
