What is the formula for the area of a rectangle?
The area of a rectangle is calculated by multiplying its length by its width (A = l × w).
What is the formula for the area of a triangle?
The area of a triangle is half of its base multiplied by its height (A = 1/2 × b × h).
What is the relationship between the radius and the diameter of a circle?
The diameter of a circle is exactly twice the length of its radius (d = 2r).
What defines two angles as supplementary?
Two angles are supplementary if the sum of their measures is exactly 180 degrees.
What is the Pythagorean theorem formula used for right triangles?
The Pythagorean theorem is a² + b² = c², where c is the hypotenuse and a and b are the legs.
How do you calculate the perimeter of any polygon?
The perimeter of a polygon is calculated by adding together the lengths of all its outer sides.
What is the formula for the area of a trapezoid?
The area of a trapezoid is A = 1/2 × (a + b) × h, where 'a' and 'b' are the parallel bases and 'h' is the height.
What are the two formulas used to calculate the circumference of a circle?
The circumference of a circle can be calculated using C = πd (pi times diameter) or C = 2πr (two times pi times radius).
What is the formula for the volume of a cylinder?
The volume of a cylinder is V = πr²h, which is the area of its circular base multiplied by its height.
How do you calculate the volume of a rectangular prism?
The volume of a rectangular prism is calculated by multiplying its length, width, and height (V = l × w × h).
