100

Any number from the set of numbers represented by {1, 2, 3, ........}.  This kind of number is sometimes referred to as a natural number or a positive integer.

What is a counting number?

100

A triangle in which an interior angle is 90 degrees (right angle).

What is a right triangle?

100

The property that asserts that the grouping of adjacent addends or factors does not change the sum or product.  Example:  (a + b) + c = a + (b + c)

What is the associative property of addition or multiplication?

100

A polygon with exactly four sides.

What is a quadrilateral?

100

A graph that represents the real numbers as ordered points on a line.  May be either horizontal or vertical.  Starting at 0, the numbers on the right are positive and the numbers on the left are negative.

What is a number line?

200

A counting number, the additive inverse (negative) of a counting number or zero.  Any number from the set of numbers represented by {.....-3, -2, -1, 0, 1, 2, 3,.......}.

What is an integer?

200

A triangle in which an interior angle is greater than 180 degrees (obtuse angle).

What is an obtuse triangle?

200

The property that asserts that the order of adding adjacent addends or multiplying adjacent factors does not affect the sum or product.  Example:  a x b = b x a

What is the commutative property of addition or multiplication?

200

A quadrilateral in which opposite sides are parallel and congruent.

What is a parallelogram?

200

Two or more lines that lie in the same plane and never intersect.

What are parallel lines?

300

Any number greater than zero.

What is a positive number?

300

A triangle where all sides are congruent (same length). Each of the angles is 60 degrees.

What is an equilateral triangle?

300

The property that states that any number times zero always equals zero.

What is the zero property?

300

A parallelogram with all sides congruent.

What is a rhomubs?
300

A part of a line that has one endpoint and continues infinitely in one direction or on one side of that point. Identified by its endpoint and another unique point on this.

What is a ray?

400

The additive inverse of a number.

What is the opposite?

400

A triangle with two congruent sides, which are called legs.  The angles opposite the two legs are also congruent.

What is an isosceles triangle?

400

The property that states that any number times one always equals that number.

What is the identity property?

400

A quadrilateral with exactly one pair of parallel sides.

What is a trapezoid?

400

A portion of a line bounded by two endpoints.  This is identified by its endpoints.

What is a line segment?

500

Any number that can be written as a fraction.  Includes all of the integers, since all integers can be written as that number over one.

What is a rational number?

500

A triangle with no congruent sides.  (All sides have different lengths.)

What is a scalene triangle?

500

When a single-term expression is being multiplied by a sum or difference, the single-term expression can be multiplied by each term before finding the sum or difference.  Example:  5(7 + 4) = 5(7) + 5(4) = 35 + 20.

What is the distributive property?

500

True or False?  A square is a rectangle.

What is true?

500

Lines that intersect to form a right angle(s).

What are perpendicular lines?
