AI Math SolverA right triangle has exactly one 90-degree angle. Learn the definition, the names of its sides (legs and hypotenuse), and the Pythagorean theorem that defines its side lengths.
Solve it with the AI Math SolverThe defining feature of a right triangle is its single right angle. The two sides forming that angle are the legs; the side opposite it — always the longest — is the hypotenuse.
Right triangles are governed by the Pythagorean theorem and host the basic trigonometric ratios (sine, cosine, tangent). Special cases like the 30-60-90 triangle have fixed side ratios.
A right triangle is a triangle with exactly one 90-degree (right) angle. The side opposite that angle is the hypotenuse; the other two sides are the legs.
The Pythagorean theorem: a² + b² = c², where a and b are the legs and c is the hypotenuse. It works only for right triangles.
