What is the formula for the area of a triangle?

Back

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

Front

What is the Pythagorean theorem?

Back

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.

How do you calculate the circumference of a circle?

Back

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

What is the relationship between the angles in a triangle?

Back

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

Front

What is the formula for the volume of a rectangular prism?

Back

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

Front

What is the difference between a radius and a diameter?

Back

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.

What is the formula for the area of a circle?

Back

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

Front

What is a complementary angle?

Back

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

Front

What is a supplementary angle?

Back

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

How do you find the area of a trapezoid?

Back

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