To determine the missing sides of a right triangle given the hypotenuse and the angles of a right triangle, the first thing to do is to determine the missing variables, then, compare this with the formula for the sine and cosine functions. From this, we can ge...
A right triangle is one of the three triangles classified by their angles. This triangle has the condition that the two legs form an angle of 90{eq}^{\circ} {/eq}. We can apply the Pythagorean theorem if we have the length of two of its sides. The Pythagorean theorem is as...

Theperimeterof a shape is the length around the outside of that shape.Because a triangle's outside is composed of three lines, you can find its perimeter by adding the lengths of these lines.If you know only the lengths of two sides of a right triangle, you can use the Pythagorean The...
One side of a right triangle is always longer than the other two sides. This long side is known as the hypotenuse and will always be opposite the right angle of the triangle. The other two sides of the triangle are referred to as the legs. ...
