Best Answer

A right triangle is a triangle that includes a 90° angle.

Right triangles are significant because you can apply trigonometric functions and the Pythagorean theorem to them to find unknown side lengths or angles.

  • sinA = cosB = a/c
  • cosA = sinB = b/c
  • tanA = a/b
  • a2 + b2 = c2
