RIGHT TRIANGLES

In geometry, is called every triangle right triangle with a right angle, ie an angle of 90 grados.1 The ratios of the lengths of the sides of a right triangle is an approach of plane trigonometry. In particular, a right triangle is defined by the Pythagorean theorem.

A right triangle tour, having as one of its legs axis as its hypotenuse generator generates a cone of radius equal to the non-axial leg and height equal to the axial leg.

If two triangles similar rectangles generate two cones, under the conditions of the preceding sentence, then their volumes are proportional to the cubes of any two corresponding sides. Also, the areas are proportional to the squares of any two corresponding sides.
