Bisect - Something is divided into 2 equal halves. 

Composite numbers - A composite number is a natural number that has a factor other than 1 and itself. (Composite numbers: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81,82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.)

Coincident: lie on the exact same point or line

Colinear: 3 points are said to be colinear if the lie on the same straight line

Constant - a constant is a number on it's own.

Equidistant - Equal distance apart. (point a and point b are both 5 units away from point c so they are equidistant).

Integer - The integers are the “whole numbers” including those with negative sign ⋯-3, -2, -1, 0, 1, 2, 3⋯. In Latin, the word integer means “whole.” The set of integers is usually denoted by Z. Integers are basic building blocks in mathematics.

Locus of points - A locus is the set of all points (usually forming a curve or surface) satisfying some condition. ie) a set of points may be equidistant from the origin at a radius then y^2 +x^2 =2

Parallel - Two lines that will never meet. Two lines will have the same slope if they are perpendicular.

Perpendicular - at right angles to or at 90 degrees. Two lines are perpendicular if their slopes are negative reciprocals

Prime numbers - A prime number is a natural number greater than 1 that has no factor other than 1 and itself. (Prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97)

Rational number - an integer or represented as a fraction that involves two integers. 5/7 is a rational number.

Reciprocal - Two numbers that multiplied together equal 1 (1/2 multiplied by 2 are reciprocals). Negative reciprocal multiplies to give negative 1.

Respectively - separately or individually and in the order already mentioned (used when enumerating two or more items or facts that refer back to a previous statement): Ben and Sam recieved $10 and $15 respectively means that Ben got $10 and Same got $15

Triangles - a 3 sided polygon that can be defined by various features

• Equilateral - all 3 sides are equal

• Isosceles - 2 of the sides are equal

• Scalene - all sides are different 

• Right angled - Has a 90 degree angle
