Written as a number inside vertical lines:  =3 and [-3]=3. absolute value An angle measuring less than 90°. A triangle with three of these is called a ______ triangle. acute angle Two line segments coming together at a point called the vertex. angle A measure, in square units, of the size of a region in a plane. Finding the _____ of a figure usually involves multiplying two dimensions, such as length and width or base and height. The _____ of a circle is found by multiplying pi by the square of the radius. area An integer that has more factors than one and itself; i.e., a nonprime integer greater than 1. The first ten are 4,6,8,9,10,12,14,15,16,18. composite Two angles whose measures add up to 90 degrees.  ex.- A 30 degree angle and a 60 degree complementary angles A solid generated by rotating a right triangle about one of its legs cone;also called right circular cone. A rectangular solid whose faces are all squares. cube A line segment formed by the intersection of two faces of a three-dimensional shape. edge A number to be divided  (e.g. in 12/3= 4 it is 12) dividend A number that divides into another number divisor An oval shape, literally a set of points in a plane for which the sum of the distances from two points (called foci) is constant ellipse A triangle with three equal sides and three equal angles of 60 degrees. equilateral triangle a polygon formed by edges of a solid face A positive integer that divides into n with no remainder factor (of n)  ( eg. factors of 18 is 1,2,3,6,9,18) The side of a right triangle opposite the right angle. Also the longest side. hypotenuse A number that cannot be represented on the number line because it contains a factor of i imaginary number Any of the natural numbers (also known as "whole numbers"), the negatives of these numbers, or zero. integer A triangle with two sides of equal length isosceles triangle The two sides of a right triangle that are not the hypotenuse (i.e. are not opposite the right angle) legs A number that n will divide into with no remainder. Some of the multiples of 18 are 0,18,36, 54,72, and 90. multiple (of n) .remove_background_ad { border: 1px solid #555555; padding: .75em; margin: .75em; background-color: #e7e7e7; } .rmbg_image { max-height: 80px; } AuthorBubbles83 ID330088 Card SetMathematical terms and concepts MAT A DescriptionMathematical terms and concepts for MAT Updated2017-04-03T21:10:54Z Show Answers
