Octagon – Definition, Types, Formula, Properties, Examples What is an Octagon ? An octagon is a geometric shape that has eight sides and eight angles. The word “octagon” comes from the Greek words “okto,” meaning eight, and “gonia,” meaning angle. Here are some key characteristics of an octagon. Definition: An octagon is a polygon with […]

Read More →Alternate Angles: Definition and Types In this tutorial we will learn definition and types of alternate angles. In geometry, alternate angles are a special kind of angles. Alternate interior angles are formed when a transversal intersect two parallel or non-parallel lines. If a straight line intersects two lines, in the same plane at two distinct […]
Read More →Alternate Interior Angles – Definition – Examples – Properties What are alternate interior angles? The term alternate interior angles is often used when two lines are intersected by a third line(transversal). Alternate interior angles are formed when two lines are intersected by a third line. The third line is known as the transversal line. Alternate […]

French Mathematician Rene Descartes trying to solve the problem of describing the position of a point on a plane with the Cartesian coordinate system and the cartesian plane. In Cartesian coordinate system, we derive a vertical and a horizontal line. When we […]
Read More →Regular polygon A polygon which has all sides are congruent(equal) and all angles are congruent (equal) is known as a regular polygon. If a triangle has all the sides are same and all the angles are same then it is a equilateral triangle or a regular triangle. If a quadrilateral has all the sides are same […]
Read More →Type of Bar Graphs In this lesson, we will learn about bar graph or bar chart. We also focus on the different type of bar graphs, definition of bar graph how to create bar graphs. A graphical representation of data, in which bars show comparisons between categories of data.A […]
Read More →Cartesian Coordinate System Cartesian Coordinate system developed in seventeenth century by Rene Descartes the great French philosopher and mathematician. Cartesian Coordinate system, also called rectangular Coordinate system and used to position of points on a two dimensional or three dimensional plane. Let’s briefly learn about Cartesian Coordinate system. Cartesian Coordinate plane The plane is called Cartesian plane […]
