Grade 8 Math Practice

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a quadrilateral with one pair of parallel sides and the non-parallel sides being equal in length.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are always the same distance apart and never meet, regardless of how far they are extended.

Front

How do you calculate the volume of a cylinder?

Back

The volume V of a cylinder can be calculated using the formula: V = πr²h, where r is the radius and h is the height.

Front

What is the distance formula for two points in a coordinate plane?

Back

Front

What transformations can show that two shapes are similar?

Back

Two shapes can be shown to be similar through transformations such as dilation, rotation, reflection, and translation.

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables, with points representing individual data points.

Front

What does a negative linear association in a scatterplot indicate?

Back

A negative linear association indicates that as one variable increases, the other variable tends to decrease.

Front

What is the definition of dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

What is the definition of reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the definition of rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.
