What is a linear relationship in mathematics?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph. It has a constant rate of change.

Front

How do you calculate the area of a parallelogram?

Back

Area = base × height.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

How do you find the area of a trapezoid?

Back

Area = (1/2) × (base1 + base2) × height.

Front

What is a circle graph (pie chart)?

Back

A circle graph is a circular chart divided into sectors, each representing a proportion of the whole.

Front

How do you calculate the percentage of a part compared to a whole?

Back

Front

What is a similar triangle?

Back

Similar triangles are triangles that have the same shape but may have different sizes. Their corresponding angles are equal, and their sides are in proportion.

Front

How do you determine if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are equal or if the sides are in proportion.

Front

What is the formula for calculating the slope of a line?

Back

Slope (m) = (change in y) / (change in x).

Front

What does it mean for a graph to be increasing?

Back

A graph is increasing when the y-values rise as the x-values increase.
