Question 1

Coordinate Plane / Graph / Grid

Answer 1

A grid with the x-axis and the y-axis.

Question 2

Scale Model

Answer 2

The ratio of the length in a drawing or model to the length of the real thing.

Question 3

Similar Figures

Answer 3

Two shapes are similar if the only difference is size and possibly the need to turn or flip one around.

Question 4

Corresponding Sides

Answer 4

If the relative position of two sides is same in two figures, then they are called corresponding sides.

Question 5

Corresponding Angles

Answer 5

When two parallel lines are crossed by another line, the angles in matching corners are called corresponding angles.

Question 6

Inverse Operations

Answer 6

The operation that reverses the effect of another operation.

Question 7

Comparison

Answer 7

A statement stating the difference between two or more numbers or between decimals/fractions.

Question 8

Property of One

Answer 8

In multiplication, the product of any number and 1 is that number (2 X 1 = 2). In division, any number divided by 1 will equal that number (3/1 = 3).

Question 9

Factor of Change

Answer 9

The factor that changes a number. (ex: 3 times 4 equals 12. So, times 4 is the multiplier that changes the 3 into 12)
