What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

How do you calculate the perimeter of a square?

Back

The perimeter of a square is calculated by adding the lengths of all four sides, or by using the formula: Perimeter = 4 × side length.

Front

If 4 notebooks cost $12, what is the cost of 1 notebook?

Back

The cost of 1 notebook is $3, calculated by dividing the total cost by the number of notebooks: $12 ÷ 4 = $3.

Front

What is the formula for the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation: y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the y-intercept of the function y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

How do you solve the equation 3x + 5 = 20?

Back

To solve for x, subtract 5 from both sides to get 3x = 15, then divide by 3 to find x = 5.

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.

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: Perimeter = 2 × (length + width).

Front

How do you find the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
