5 Matching Questions

1. reflection
2. vertical axis
3. origin
4. translation
5. variable
1. a
The zero point in a coordinate system. On a number line, the origin is the point at 0. On a coordinate grid, the origin is the point (0,0) where the two axes intersect.
2. b A transformation in which every point in the image of a figure is at the same distance in the same direction from its corresponding point in the figure. Informally called a slide.
3. c A letter or other symbol that represents a number. A variable can represent a single number, as in : 5 + n = 9, because only n= 4 makes the sentence true. A variable may also stand for many different numbers, as in x + 2 < 10, because any number x less than 8 makes the sentence true. In formulas and properties, variables stand for all numbers.
a + 3 = 3 + a for all numbers a.
4. d
A transformation in which the image of a figure is a mirror image of the figure over a lone of reflection. Informally called a flip.
5. e Upright; perpendicular to the horizon.

5 Multiple Choice Questions

1. A strategy for finding the area of a polygon in which one or more rectangles are drawn around all or parts of the polygon through its vertices. The sides of the drawn rectangle(s), together with the sides of the original figure, define regions that are either rectangles or triangular halves or rectangles. Add and/or subtract the areas of these rectangular and triangular regions to get the area of the original polygon.
2. The axis extending from left to right-Often named the x axis. Perpendicular to the vertical or y axis.

3. 1. One of the sides of a rectangle.
2. The length of this side. The area of a rectangle is the length of the base times the altitude, or height

4. 1. A number used to locate a point on a number line; a point's distance from an origin.
2. One of the numbers in an ordered pair or triple that locates a point on a coordinate grid or coordinate space, respectively.
5. A unit to measure area. A model of a square unit is a square with each side a related unit of length. For example, a square inch is the area of a square with 1-inch sides. Square units are often labeled as the length unit squared.

5 True/False Questions

1. quart (qt)
A U.S customary unit of volume or capacity equal to 8 fluid ounces or 1/2 pint.

2. liter (L)
A U.S customary unit of volume or capacity equal to 8 fluid ounces or 1/2 pint.

3. area
The amount of surface inside a 2-dimensional figure. Area is measured in square units such as square miles, square inches, or square centimeters.

4. height (of a rectangular prism)
The length of the shortest line segment from a base of a prism to the plane containing the opposite base.

5. formula
1. The amount of space occupied by a 3-dimensional figure. Same as capacity.
2. The amount a container can hold. Volume is often measured in cubic units, such as cubic inches or cubic feet.
