Congruent Triangles - Hypotenuse Leg Theorem The hypotenuse is the side opposite the right angle, and it’s always the longest side in a right triangle One pair of corresponding legs of the triangles must be congruent
Pythagorean Theorem Calculator Find a missing side or check if 3 sides make a right triangle with clear steps, tolerance control, and input validation
Hypotenuse Calculator You cannot solve a right-angled triangle with only the hypotenuse This is because the other two sides and angles are still undefined, so the triangle can still have many forms
The Pythagoras Theorem (Pythagorean Theorem) - Formula, Proof . . . The other two sides that are adjacent to the right angle are called the legs of the triangle Let a = 3, b = 4 be the legs and c = 5 be the hypotenuse of a right triangle The Pythagoras Theorem states that for right triangles with legs of lengths a and b and hypotenuse of length c, a 2 + b 2 = c 2
