1

## X-axis

### the horizontal number lin eon the coordinate grid

2

## Y-axis

### the vertical number line on the coordinate grid

3

## origin

### the point where the x-axis and the y-axis cross

4

## quadrant

### the four regions on the coordinate grid

5

## coordinates are values in a...

### ordered pair

6

## Vertex

### a point where two sides of a figure meet

7

## the plural of vertex is

### vertices

8

## the movement of a geometric figure is called a

### transformation

9

## translation

### a slide along a straight line

10

## reflection

### a mirror image

11

## a turn about a fixed point is called a

### rotation

12

## to approximate an answer is to

### estimate

13

## Overestimating is when

### the estimate is larger than the actual answer

14

## Underestimating is when

### estimating a number that's smaller than the actual answer

15

## How does adding a zero after the decimal point change the value? For example, 2.3 and 2.30

### It does not change the value. 2.3 is worth the same amount as 2.30

24

## the line that divides an angle into two equal parts

### angle bisector

25

## an angle that is greater than 90 degrees is called

### obtuse

26

## a side of a two dimensional closed figure is called the

### base

27

## the perpendicular distance from the base to the oppositte side

28

## 'h' is the symbol for

### height

29

## what does percent mean?

### out of 100

30

## a decimal number with a digit or group of digits that repeats forever is called a

### repeating decimal

31

## a decimal number in which the digits stop

### terminating decimal

32

## probability

### the likelihood or chance of an event occuring

33

## the equation for probability is

### favourable outcomes / possible outcomes

34

## outcome

### one possibility result of a probability experiment

35

37

## tree diagrams are used to

### organize outcomes

38

## random

### an event in which every outcome has an equal chance of occuring

39

40

## the expected probability of an event occurring is called the

### theoretical probability

41
