What is the height of an equilateral triangle with side length s?

Back

The height h of an equilateral triangle can be calculated using the formula: h = \frac{\sqrt{3}}{2} s.

Front

How do you find the length of each side of an equilateral triangle given its height?

Back

To find the side length s from the height h, use the formula: s = \frac{2h}{\sqrt{3}}.

Front

What is the formula to find the area of a triangle?

Back

The area A of a triangle can be calculated using the formula: A = \frac{1}{2} \times base \times 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): c^2 = a^2 + b^2.

How do you solve for x in a linear equation?

Back

To solve for x in a linear equation, isolate x on one side of the equation using inverse operations.

Front

What is the formula for the circumference of a circle?

Back

The circumference C of a circle is given by the formula: C = 2\pi r, where r is the radius.

What is the formula for the area of a circle?

Back

The area A of a circle is given by the formula: A = \pi r^2, where r is the radius.

Front

How do you find the value of y in a proportion?

Back

In a proportion \frac{a}{b} = \frac{c}{y}, you can find y by cross-multiplying: y = \frac{b \cdot c}{a}.

Front

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

Back

The volume V of a rectangular prism is given by the formula: V = length \times width \times height.

Front

What is the relationship between the angles in a triangle?

Back

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