Rule for 45 45 90 triangle
Aug 9, 2023 · A 45-45-90 triangle is a special type of right triangle where the two legs are congruent, meaning they have the same length, and the angles opposite the legs are both 45 degrees. The third angle, opposite the hypotenuse, is a right angle (90 degrees). The key rule for a 45-45-90 triangle is the relationship between the lengths of the sides. If ... 45-45-90 Triangle. A 45-45-90 triangle is a special right triangle. The other type of special right triangle is 30-60-90. These numbers represent the degree measures of the angles. The reason these triangles are considered special is because of the ratios of their sides - they are always the same! Special right triangles hold many applications ...

As a 45 45 90 triangle has two equal shorter sides, the second side will also be 5 cm. Length of side a = 5cm (given) Length of side b = 5cm (assumed) Length of longest side = 7.07 cm. The area of 45 45 90 triangle is given as under: A r e a = a 2 / 2. A r e a = 5 2 / 2. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another. The basic 30-60-90 triangle ratio is: Side opposite the 30° angle: x. Side opposite the 60° angle: x * √ 3. Side opposite the 90° angle: 2 x.
