A detailed tutorial on how to identify octagons. Step by step tutorial including several examples of identifying octagons for reference.
Overview
An octagon is any polygon that has eight sides. Octagons can either be regular or irregular. Regular octagons are close to the shape of a circle with 8 straight edges. Irregular octagons are any other shape that has eight sides, provided that it is still considered a polygon.

A detailed tutorial on how to identify heptagons. Step by step tutorial including several examples of identifying heptagons for reference.
Overview
A heptagon is any polygon that has seven sides. Heptagons can either be regular or irregular. Regular heptagons are close to the shape of a circle with 7 straight edges. Irregular heptagons are any other shape that has seven sides, provided that it is still considered a polygon.
Description
A detailed tutorial on how to identify hexagons. Step by step tutorial including several examples of identifying hexagons for reference.
Overview
A hexagon is any polygon that has six sides. Hexagons can either be regular or irregular. Regular hexagons are close to the shape of a circle with 6 straight edges. Irregular hexagons are any other shape that has six sides, provided that it is still considered a polygon.
Description
A detailed tutorial on how to identify pentagons. Step by step tutorial including several examples of identifying pentagons for reference.
Overview
A pentagon is any polygon that has five sides. Pentagons can either be regular or irregular. Regular pentagons are close to the shape of a house. Irregular pentagons are any other shape that has five sides, provided that it is still considered a polygon.
Description
A detailed tutorial on symmetry and symmetric images. Step by step tutorial including several examples of symmetry for reference.
Overview
Symmetry is a very basic concept in geometry. It is similar to invariance. It is when something is equal to itself through both of its sides. If you compare the two sides of something and they match, then the object is said to be symmetric. When testing an image for symmetry, the easiest test is to draw an imaginary line down the middle. Then pretend to fold the image over. If the two sides are perfect matches of each other, then the image is symmetric.
Description
A detailed tutorial on how to solve vectors using vector subtraction. Step by step tutorial including several examples of vector subtraction for reference.
Overview
Vector subtraction involves two vectors that do not have to be equal, and could have different magnitudes and directions. The vectors are referred to as a and b. The formula for vector subtraction is:
In general, vector subtraction is defined geomtrically instead of algebraically, so it is not used quite as often as vector addition is.
Description
A detailed tutorial on vector space. Step by step tutorial including several examples of vector space and how to solve for vector space for reference.
Overview
Vector space is simply a structure in mathematics that is formed by a collection of vectors. Vector space can be calculated using vector addition and scalar multiplication. Vector space is very dependent on the definition of a vector. Some vectors are simply arrows on a fixed plane. But in general, the term vector just means there is an object for which two operations can be performed. The definition of vector space is defined in algebraic terms, as opposed to the geometric terms that can sometimes be applied.
Description
A detailed tutorial on the intial side of an angle. Step by step tutorial including several examples of the initial side of an angle for reference.
Overview
The initial side of an angle is the side of an angle where the measurement begins. An angle is always measured from the degree of zero to the degree of the angle, regardless of if the angle is positive or negative. The best display of an initial side would be when you draw angles with a protractor – the line that you trace along the bottom of your protractor forms a ray which is known as the initial side.
Description
A detailed tutorial on the terminal side of an angle. Step by step tutorial including several examples of the terminal side of an angle for reference.
Overview
The terminal side of an angle is the side of an angle where the measurement ends. An angle is always measured from the degree of zero to the degree of the angle, regardless of if the angle is positive or negative. The best display of a terminal side would be when you draw angles with a protractor – the line that you draw for your degree forms a ray which is known as the terminal side.
Description
A detailed tutorial on how to find values of quadrantal angles. Step by step tutorial including several examples of finding values of quadrantal angles for reference.
Overview
Quadrantal angles have a terminal side coinciding with a coordinate axis. A trigonometric functional value of such an angle can be determined by the coordinates of the point where the terminal side intersects the unit circle. When on the unit circle, the Cartesian coordinate (x, y) cooresponds to (cos(&), sin(&)) on the unit circle.
