WebThe side opposite the right angle of a right triangle is called the hypotenuse. The sides that form the right angle are called legs. The hypotenuse is the longest side of the right … WebFirst, remember that the three angles in any triangle add up to 180 degrees. If the angles are x, y, and z, then: x + y + z = 180. Next, remember that the largest angle is 90 degrees (let’s say that angle is z). Then: x + y + 90 = 180. x + y = 90. Then, recall that the two smaller angles have the same measure. WebThe ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
