Congruent angles

Two angles that have the same measure


Conjecture

A wellthought out guess,prediction or estimate


Coordinate system

A graph with a horizantal number line (x axis) and vertical number line (y axis) that are perpendicular to each othe. The point of orgin is labeled 0 on the graph. An ordered pair (x,y)is used to name a point on the coordinate system


Counting

1,2,3,4(naming the sequence of numbers)


Cube

A rectangular solid with six congruent square faces

In a polygon, a segement that connects one vertexs to another vertex but is not a side of the polygon


Diameter

In a circle, a segment that passes through the center and has its endpoints on the circle


Difference

The answer for subtractio. in 16 7 = 9, 9 is the difference


Distributive property of multiplication and addition

The product of a number and the sum of two number equals the sum of two products. 3 x (4 + 2)= (3 X 4) + (3 X 2)


Dividend

A number that is divided by another and the remainder is 0, the first number is divisible by the second number
