Overview of Sides and Bases of Polyhedrons
Description
A detailed tutorial on sides and bases of polyhedrons. Step by step tutorial including several examples of sides and bases of polyhedrons for reference.
Overview
Sides and bases of polyhedrons are more commonly known as faces of 3D geometrical shapes. Typically on a polyhedron you will have 2 bases and several sides, although there are exceptions to that rule. The cylinder only has one side, and the triangular prism, or pyramid, only has one base. You can identify the base because it is a unique shape on the polyhedron. Everything else is a side. This only applied to your normal polyhedron shapes such as prisms.

How to Identify Pythagorean Triples
Description
A detailed tutorial on Pythagorean triples. Step by step tutorial including several examples of Pythagorean triples for reference.
Overview
A Pythagorean triple is a set of three numbers that make up a right triangle. They are the measure of the sides, not the measure of the angles. This you should know by looking at the name. The Pythagorean theorem deals with only the sides of the right triangle, so Pythagorean triples should also only deal with the sides of a right triangle. All the numbers must be integers, and they must be positive. They are written rather like coordinates are, in a (a, b, c) pattern. A common example is is (3, 4, 5). From any triple, any other triple can be found. If (a, b, c) is a triple, then (ka, kb, kc) also must be a triple, according to the rule of similar triangles.

How to Identify Decagons
Description
A detailed tutorial on how to identify decagons. Step by step tutorial including several examples of identifying decagons for reference.
Overview
A decagon is any polygon that has ten sides. Decagons can either be regular or irregular. Regular decagons are close to the shape of a circle with 10 straight edges. Irregular decagons are any other shape that has ten sides, provided that it is still considered a polygon.

All About 30-60-90 Triangles
Description
A detailed tutorial on the solving of 30-60-90 triangles. Step by step tutorial including several examples of how to solve 30-60-90 triangles for reference.
Overview
A 30-60-90 triangle is a special type of right triangle. The 30-60-90 refers to the measure of the angles of the triangle. This triangle is special because if you take two of them, flip one of them over, and place the triangles back to back, then you have an equilateral and equiangular triangle – triangles that have sides and angles all of the same length.

All About 45-45-90 Triangles
Description
A detailed tutorial on the solving of 45-45-90 triangles. Step by step tutorial including several examples of how to solve 45-45-90 triangles for reference.
Overview
A 45-45-90 triangle is one of the few special triangles that the angles are always the same on – the 45-45-90 part refers to the measurement of the angles. A 45-45-90 triangle is special because it is the only right triangle where the other two angles are equal. Because the angles are equal, this also means that those sides are of equal lengths.
