Mathematical terms and concepts MAT A

  1. The magnitude of a number, irrespective of its sign. Written as a number inside vertical lines: [3] =3 and [-3]=3.
    absolute value
  2. An angle measuring less than 90°. A triangle with three of these is called a ______ triangle.
    acute angle
  3. Two line segments coming together at a point called the vertex.
    angle
  4. 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
  5. 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
  6. Two angles whose measures add up to 90 degrees.  ex.- A 30 degree angle and a 60 degree
    complementary angles
  7. A solid generated by rotating a right triangle about one of its legs
    cone;also called right circular cone.
  8. A rectangular solid whose faces are all squares.
    cube
  9. A line segment formed by the intersection of two faces of a three-dimensional shape.
    edge
  10. A number to be divided  (e.g. in 12/3= 4 it is 12)
    dividend
  11. A number that divides into another number
    divisor
  12. 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
  13. A triangle with three equal sides and three equal angles of 60 degrees.
    equilateral triangle
  14. a polygon formed by edges of a solid
    face
  15. A positive integer that divides into n with no remainder
    factor (of n)  ( eg. factors of 18 is 1,2,3,6,9,18)
  16. The side of a right triangle opposite the right angle. Also the longest side.
    hypotenuse
  17. A number that cannot be represented on the number line because it contains a factor of i
    imaginary number
  18. Any of the natural numbers (also known as "whole numbers"), the negatives of these numbers, or zero.
    integer
  19. A triangle with two sides of equal length
    isosceles triangle
  20. The two sides of a right triangle that are not the hypotenuse (i.e. are not opposite the right angle)
    legs
  21. 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)
