In other words, a rhombus is a parallelogram with adjacent sides of equal length. What is line of symmetry ? The […]

Vertical Line: Definition, Formula, Equation, Properties and Examples What is a Vertical Line? 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 […]

Right Angle – Definition, Example and Properties What is a right angle? When two straight lines are perpendicular to each other or intersect at 90º, they form a right angle. A right angle is represented by the symbol L. In our daily life we can see many real-life examples of the right angles. We can […]

Frequency Polygon  A frequency polygon is very similar to a histogram and represents the graphical form of data. A frequency polygon is used to show a cumulative frequency distribution or compare to sets of data.  In a frequency polygon the number of observations is marked at the the midpoint […]

Plot Points on Cartesian Coordinate System Example: Plot the point (2, 3) and identify its position in which quadrant is located. First we will place a dot at the intersection of X and Y axis, which is the center of the Cartesian coordinate and known as the origin. From the origin, move 2 units going right. Our point is […]
