Praxis 7813 Key Terms 100% Correct
1. acute angle a slight angle measuring less than 90 degrees
2. addend a number which is added to another number
3. addition combining two or more numbers and finding the total or sum
4. adjacent (angle next to or adjoining; two adjacent angles share a common side and a common
and side) vertex and do not overlap. two sides are adjacent when they share a common
vertex and the same angle
, Praxis 7813 Key Terms 100% Correct
5. algebra the study of mathematical symbols and the rules for manipulating the symbols
6. alternate angle two nonadjacent angles formed on opposite sides of a line intersecting two other
lines. if the two lines are parallel, then the alternate angles are congruent
7. angle a figure formed by two rays that share a common endpoint. each ray is the side
of the angle and the common endpoint is the vertex.
8. area the size of a surface
9. arithmetic a branch of mathematics dealing with the properties and manipulation of num-
bers -- especially addition, subtraction, multiplication, and division
10. associative prop- a property stating that you can add or multiply numbers together, regardless of
erty how they are grouped
, 11. base a foundation or something from which other things extend
12. bisect divide into two parts
13. brackets symbols used to group things. there are three types of brackets: curly brackets {
}, square or box brackets [ ], and parentheses or curved brackets ( )
14. cardinality a measure of the number of items in a set
15. chord a straight line segment whose endpoints lie on a circle
16. circle a closed shape where the set of all points in a plane are at a given distance from
a given point (center)
