The 30 - 60 - 90 theorem is a geometric theorem that applies to right triangles with angles of 30 degrees, 60 degrees, and 90 degrees. The theorem states that in such a triangle, the hypotenuse is twice as long as the side opposite the 30-degree angle, and the side opposite the 60-degree angle is √3 times as long as the side opposite the 30-degree angle.
The right triangle theorem, also known as the Pythagorean theorem, states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written algebraically as c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.
