Special right triangles calculator 30 60 90

Like the 30В°-60В°-90В° triangle, knowing one side length allows you to determine the lengths of the other sides of a 45В°-45В°-90В° triangle.Д¤5В°-45В°-90В° triangles can be used to evaluate trigonometric functions for multiples of ПЂ/4.Special right triangles are right triangles with additional properties that make calculations involving them easier. The 45В°-45В°-90В° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which the sides corresponding to the angles, 45В°-45В°-90В°, follow a ratio of 1:1:в€љ 2. This type of triangle can be used to evaluate trigonometric functions for multiples of ПЂ/6.

Then using the known ratios of the sides of this special type of triangle: a =ДЄs can be seen from the above, knowing just one side of a 30В°-60В°-90В° triangle enables you to determine the length of any of the other sides relatively easily. For example, given that the side corresponding to the 60В° angle is 5, let a be the length of the side corresponding to the 30В° angle, b be the length of the 60В° side, and c be the length of the 90В° side.: Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio. In this type of right triangle, the sides corresponding to the angles 30В°-60В°-90В° follow a ratio of 1:в€љ 3:2. The 30В°-60В°-90В° refers to the angle measurements in degrees of this type of special right triangle. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation: A = Examples include: 3, 4, 5 5, 12, 13 8, 15, 17, etc.ДЄrea and perimeter of a right triangle are calculated in the same way as any other triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. h refers to the altitude of the triangle, which is the length from the vertex of the right angle of the triangle to the hypotenuse of the triangle. In this calculator, the Greek symbols О± (alpha) and ОІ (beta) are used for the unknown angle measures.

Their angles are also typically referred to using the capitalized letter corresponding to the side length: angle A for side a, angle B for side b, and angle C (for a right triangle this will be 90В°) for side c, as shown below. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. In a right triangle, the side that is opposite of the 90В° angle is the longest side of the triangle, and is called the hypotenuse. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry.
