Parallel lines are lines in a plane which do not meet
Partitions a mode of separating a positive whole number into a sum of positive whole numbers.
The Distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse.
The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Geometric properties is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.
Radicals is simplified, or in its simplest form, when the radicand has no square factors.
A ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other
a part cut off from a figure, especially a circular or spherical one, by a line or plane, as a part of a circular area contained by an arc and its chord or by two parallel lines or planes. Also called line segment.
A polygon is any 2 dimensional shape formed with straight lines.
A quadrilateral is a polygon.
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.
