Not regular right triangles. Isoceles and other stuff.

Two special right triangles are the 30-60-90 and 45-45-90.
With the 30-60-90 the short leg is x units in length, the long leg is x*sqrt(3) units in length and the hypotenuse is 2x units in length.
With the 45-45-90 the legs are x units in length and the hypotenuse is x*sqrt(3) in units length.

The same way you solve the other ones. You can ALWAYS use Pythagorean Theorem. But you can also memorize the ratios of the side lengths for the special ones.
on a 45-45-90 (isosceles) the ratio is 1:1:sqrt 2 meaning the sides opposite the 45 degree angles are equal, and the hypoteneuse is the side length times the square root of 2. For instance, 5:5: 5*sqrt(2)
on a 30-60-90 the ratio is 1:2:sqrt(3). The 1 goes opposite the 30 degrees, the 2 with the 90 degrees, and the sqrt(3) with the 60 degrees

this question isn't specific, google specific suitable triangles. only understand in a 40 5-40 5-ninety the ratio of the part lengths is a million to a million to Square_root(2). the different triangle has yet another ratio..

You've got to be kidding.
