acute angle - an angle that is less than 90degrees.

acute triangle-a triangle with all angle measuring less then 90 degrees

addend- a number added to another to form a sum

addition property of opposites-property that states the sum of a number and its opposite equals 0

adjacent angles- angles in the same plane that have a common vertex and side

algebraic expression- an expression that contains at least one variable {example= x+8 =? =4]

algebraic inequality- an inequality that contains at least one variable

alternate exterior angles-a pair of angles that formed by two lines intersecting by a third line {example= the letter H is a close example}
