What is the formula for finding the perimeter of a composite figure?

Back

To find the perimeter of a composite figure, add the lengths of all the outer sides together.

Front

What does a scatterplot show in relation to two variables?

Back

A scatterplot displays the relationship between two variables, indicating whether they are correlated, have no relationship, or are inversely related.

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides: a² + b² = c².

Front

How do you determine if a set of sides can form a right triangle?

Back

Use the Pythagorean theorem: check if a² + b² = c² for the given sides.

Front

What is the distance formula in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the definition of a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

How do you find the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the relationship between the sides of a right triangle?

Back

The longest side (hypotenuse) is opposite the right angle and is always longer than either of the other two sides.

Front

What does it mean if a scatterplot shows no relationship?

Back

It means that changes in one variable do not affect the other variable.
