-Square(T): A parallelogram(G) with four congruent sides and four right angles(C)

-Subtraction(T): The operation ** general class word **in which the difference between two numbers or quantities is calculated (C). Also, the inverse of addition(G)** nop **

- Set(T): A set is a collection of things(G), without regard to their order(C)

-Quadrilateral(T): A polygon(G) that has four sides(C)

-Hypotenuse(T): The side of the triangle(G) that is opposite the right angle(C)

-Chaos(T): Chaos is the breakdown** GCW ** of predictability(C), or a state of disorder(G)

-Coefficients(T): The numbers** GCW ** in front of the letters(G) in a mathematical expression, for example, in: 4d + 5t2 + 3s, the 4, 5, and 3 are coefficients for the d, t2, and s(C)

-Constants(T): In math, things that do not change(G): for example distance, volume, mass, are called constants. The things that do change are called variables(C)

-Tolerance(T): Tolerance is the amount of error(G) accepted in a given situation. See Estimator(C) -Trapezoid(T): A quadrilateral(G) with exactly one pair of parallel sides(C) 2. __**Using your own words**__, write 5 definitions about any mathematical terms.

Addition: Is the sum of two or more numbers, and is read: a plus b, with a and b two real numbers.

Square: When we made a multiplication of a number by itself, ** it **is equal to the square(a), example: 3 x 3 = 3^2 = 9 ; A x A = A^2

Leg: __there__ are the sides next to the right angle in a right triangle.

Right Angle: Is a angle that __have__** has ** 90 degrees, or in radians, π/2

Integer: Is the set of number** S ** formed by the naturals numbers plus the set formed from minus infinite to 0.
