Term
 absolute value
Definition
 the magnitude of a number, irrespective of its sign. Written as a number inside verical lines I3I = 3 and I-3I = 3
Term
 acute angle
Definition
 an angle measuring less that 90 degrees. a Triangle with three acute angles is called an acute triangle.
Term
 composite number
Definition
 an integer that has more factors than one and itself; i.e., a nonprime integer greater than 1.
Term
 complementary angles
Definition
 two angles whose measures add up to 90 degrees.
Term
 edge
Definition
 a line segment formed by the intersection of two faces of a three-dimensional shape.
Term
 dividend
Definition
 a number to be divided.
Term
 divisor
Definition
 a number that divides into another number
Term
 ellipse
Definition
 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.
Term
 equilateral triangle
Definition
 a triangle with three equal sides and three equal angles of 60 degrees.
Term
 face
Definition
 a polygon formed by the edges of a solid.
Term
 hypotenuse
Definition
 the side of a right triangle opposite the right angle. Always the longest side. If c is the hypotenuse and a and b are the legs of the right triangle, then c2 = a2 + b2
Term
 imaginary number
Definition
 a number that cannot be represented on the number line because it contains a factor of i,
Term
 legs
Definition
 The two sides of a right triangle that are not the hypotenuse (i.e., are not opposide the right angle).
Term
 obtuse
Definition
 An angle that meausres more than 90 degrees and less than 180. An obtuse triangle is one that has one obtuse angle.
Term
 parallelogram
Definition
 A quadrilateral with two parallel sides.
Term
 perimeter
Definition
 The sum of the lengths of the sides of a polygon. Two polygons with same area do not necessarily have the same perimeter.
Term
 pi
Definition
 An irrational number represented by symbol. App. 3.14. Area of a circle - pi r 2.
Term
 Circumference of a circle
Definition
 2 pi r
Term
 r
Definition
Term
 prime number
Definition
 An integer greater than 1 that has no factors other than 1 and itself. The first ten are 2, 3, 5, 7, 11, 13, 17, 23, 29, and 31.
Term
 Pythagorean theorem
Definition
 the rule that states, "For any right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse."
Term
Definition
 square root symbol. With a little number written in, it represents a higher root.
Term
Definition
 The length of a line segment connecting the center and a point on a circle. The radius is half the diameter.
Term
 real
Definition
 Having a place on the number line..
Term
 reciprocals
Definition
 A pair of numbers whose product is 1. To get reciprocal of a fraction, switch the numerator and denominator.
Term
 rhombus
Definition
 A quadrilateral with four equal sides.
Term
 scalene triangle
Definition
 A triangle with sides of different lengths. A 3-4-5 triangle is a scalene triangle.
Term
 supplementary angles
Definition
 Two angles whose measures add to 180 degrees.
Term
 trapezoid
Definition
 A quadrilateral with two parallel sides and two nonparallel sides.
Term
 torus
Definition
 A doughnut shaped surface generated by a circle rotated about an axis in its plate that does no intersect the circle.
