Front

What is the opposite of a number?

Back

The opposite of a number is the number that is the same distance from zero on the number line but in the opposite direction.

Front

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but not necessarily the same size, meaning all pairs of corresponding angles are congruent and the ratios of corresponding sides are equal.

Front

How do you translate a point on a coordinate plane?

Back

To translate a point, you add or subtract from the x-coordinate and y-coordinate based on the direction and distance you want to move the point.

Front

What is the translation rule for moving a point (x, y) to the right and down?

Back

The translation rule is (x + a, y - b), where 'a' is the number of units to move right and 'b' is the number of units to move down.

Front

What is the square root of a number?

Back

The square root of a number is a value that, when multiplied by itself, gives the original number.

Front

What is the square root of 64?

Back

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two different parallel lines cut by a transversal.

Front

What does it mean for angles to be congruent?

Back

Angles are congruent if they have the same measure.

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a shape the same distance in the same direction.
