Chapter/Concept Chapter 13 Bar Graphs & Line Plots Vocabulary Term Definition/Meaning ExampleVertical A bar graph showing bars that are up and

down. Vertical means up and down direction.

Horizontal A bar graph showing bars that side to side.Horizontal means side to side direction.

Scale Scale shows the value of the bar. The scale could be vertical or horizontal depending on the type of bar graph.

x-axis (horizontal) The Horizontal line showing either bars or a scale depending on the type of graph. A horizontal bar graph has a scale on its x-axis and bars on its y-axis. x-axis

y-axis (vertical) The Vertical line showing either bars or scale depending on the type of graph. A vertical bar graph a scale on its y-axis and bars on its y-axis

each group

3 groups of 4 or 3 x 4Identity Property of One

The product of 1 and any number is that number

ex: 1 x 2 = 2 4 x 1 = 4 1 x 49 = 49

Identity Property The product of 0 and any number is ex: 3 x 0 = 0

of Zero always 0 0 x 6 = 0 0 x 35 = 0

Associative Property of Multiplication

When three or more numbers are multiplied, the product is always the same regardless of the grouping

ex: (3 x 2) x 4 = 24 2 x (3 x 4) = 24

Commutative Property of Multiplication

When two products are multiplied, the product is always the same regardless of the order of the factors

ex: 4 x 2 = 2 x 4 5 x 6 = 6 x 5

Vocabulary Term Definition/Meaning ExampleArea The number of square units needed to

cover the surface of a figure without any overlap.

They may be open or closed.

Polygon A closed plane figure formed by three or more line segments.

Vertex Where two line segments come together. Sometimes forming a corner or a point. The plural of vertex is vertices.

Vocabulary Term Definition/Meaning ExampleRight Angle An angle of 90°, as in a corner of a square

or at the intersection of two perpendicular straight lines.

Acute Angle An acute angle is an angle smaller than a right angle. The range of an acute angle is between 0 and 89 degrees.

Obtuse Angle The obtuse angle is more than 90° and less than 180°.

Straight Angle An angle of 180°. Has the appearance of a line, but has a point and is made up of two line segments or rays.

Vocabulary Term Definition/Meaning ExamplePoint A point is shown by a dot. A point can

be on a line, ray, or vertex

Line Segment The part of a line that connects two points. It has two definite end points. Adding the word "segment" is important, because a line normally extends in both directions without end.
