## Examples of Pythagorean Theorem

The Pythagorean theorem is one of the most commonly known formulas in mathematics. This theorem defines the relationship between the sides of a right triangle. The Pythagorean theorem is used to find the lengths of some unknown side in a right triangle. Furthermore,...

## Cross-Section of Geometric Figures

The cross-section represents the intersection of a plane with a three-dimensional object. The cross-section is the two-dimensional figure obtained by the intersection of a plane with a three-dimensional figure. For example, when a cylinder is cut by a plane that is...

## Perimeter of Geometric Figures – Formulas and Examples

The perimeter of geometric figures is one of the most important measurements of two-dimensional figures. The perimeter measures the total length of the outline of the figure. This means that the perimeter is calculated by adding the lengths of all the sides of the...

## Volume of Geometric Figures – Formulas and Examples

The volume of geometric figures is one of the most important measurements of three-dimensional figures. Volume is a measure of the space occupied by an object in three-dimensional space. Since volume is a three-dimensional measure, we use cubic units to measure it....

## Area of Geometric Figures – Formulas and Diagrams

The area of geometric figures represents the region covered by the figure in space. The area is one of the most important measurements of geometric figures. Area is a two-dimensional measure, so it has square units, such as m², cm², and so on. We can calculate the...

## Area of Regular Polygons – Formulas and Examples

The area of regular polygons is used to measure the region covered by the polygon in two-dimensional space. Since it is a two-dimensional region, we use square units to measure the area. The area of a regular polygon can be calculated using the length of its apothem...
