The area of a triangle is given by the formula: Area = 1/2 * base * height.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

The circumference of a circle is calculated using the formula: Circumference = 2 * π * radius.

The sum of the interior angles in a triangle is always 180 degrees.

The volume of a rectangular prism is calculated using the formula: Volume = length * width * height.

The radius is the distance from the center of a circle to any point on its circumference, while the diameter is twice the length of the radius, extending from one point on the circumference to another through the center.

The area of a circle is given by the formula: Area = π * radius².

Complementary angles are two angles whose measures add up to 90 degrees.

Supplementary angles are two angles whose measures add up to 180 degrees.

The area of a trapezoid is calculated using the formula: Area = 1/2 * (base1 + base2) * height.
