What is the relationship between the sides of a 30-60-90 triangle?

• In a 30-60-90 triangle, the sides are in the ratio 1:2:√3.

• In a 30-60-90 triangle, if the shorter leg is 'x', then the longer leg is 'x√3' and the hypotenuse is '2x'.

• In a 30-60-90 triangle, all sides are equal in length.

• In a 30-60-90 triangle, the hypotenuse is always the shortest side.

What is the Pythagorean theorem?

• In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides: @@a^2 + b^2 = c^2@@.

• The sum of the angles in a triangle is equal to 180 degrees.

• The area of a circle is calculated using the formula: @@A = rac{ heta}{360} imes ext{Area of the circle}@@.

• In any triangle, the longest side is always opposite the largest angle.
