Right triangles

• The hypotenuse is the longest side and it is adjacent to the right angle.
• If we know two sides of a right triangle, we can find the third using the Pythagorean theorem (c^2 = a^2 + b^2).
• In any right triangle, the sum of the squares of the legs equals the square of the hypotenuse.
• A right triangle can be identified by its angles - it has one right angle (90 degrees) and two acute angles.
• The legs of the triangle are the two sides that form the right angle.
• Tangent means opposite/adjacent
• Sine means opposite/hypoteneuse
• Cosine means adjacent/hypoteneuse
