45 4590 triangle math. In a 45 45 90 triangle you can divide the hypotenuse by the square root of 2 to find the leg. Return from 45 45 90 triangle to free geometry help. A 45 45 90 degree triangle or isosceles right triangle is a triangle with angles of 45 45 and 90 and sides in the ratio of note that it s the shape of half a square cut along the square s diagonal and that it s also an isosceles triangle both legs have the same length. Calculate the length of its base and height.

In the study of trigonometry the 45 45 90 triangle is considered a special triangle knowing the ratio of the sides of a 45 45 90 triangle allows us to find the exact values of the three trigonometric functions sine cosine and tangent for the angle 45. When given the length of the hypotenuse of a 45 45 90 triangle you can calculate the side lengths by simply dividing the hypotenuse by 2. For example sin 45 read as the sine of 45 degrees is the ratio of the side opposite the 45. The legs of such a triangle are equal the hypotenuse is calculated immediately from the equation c a 2 if the hypotenuse value is given the side length will be equal to a c 2 2.
