Properties of Rational Numbers Rational numbers Rational numbers are numbers which can be represented in the form of p/q, where p and q are any two integers and q is not equal to zero(q ≠ 0). Denominator and Numerator of a Rational Number In a rational number p/q, the integer p is the numerator and […]

Pentagon – Properties In a pentagon the sum of the internal angles is equal to 540°. In a regular pentagon each interior angle measure is 108°, and each exterior angle measure is 72°. A regular pentagon has five axes of symmetry, each one of them passes through a vertex of the pentagon and the middle […]

Alternate Exterior Angles – Definition – Examples and Properties What are alternate exterior angles? The term alternate exterior angles is often used when two lines are intersected by a third line(transversal). Alternate exterior angles are formed when two lines are intersected by a third line. The third line is known as the transversal line. Alternate […]

Horizontal Line: Definition, Formula, Properties and Examples What is a Horizontal Line? In Cartesian coordinate system, we draw a vertical and a horizontal line. (1) Y-axis is Vertical and (2) X-axis is horizontal lines on a plane. In coordinate system, meaning of horizon is a straight line that is mapped from left to right. A […]

Right Angle Triangle – Definition – Formula – Properties What is a Right Angle Triangle? A right angle triangle is a type of triangle. A right angle triangle plays an important role in trigonometry. A triangle in which one of the interior angle is 90º or a right angle is a right triangle. Right Triangle […]

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 […]
