## What are perpendicular lines?

In this article you will learn about perpendicular lines and their properties. Two lines are said to be perpendicular to each other if they lie in the same plane and meet each other at right angles (90 degrees). You will also learn to construct perpendicular lines and to measure distances with the help of perpendicular lines.

## Understanding Powers and Roots

In this article you will learn about powers and roots in maths. The power of a number indicates the number of times a number is to be multiplied by itself. Root on the other hand is the opposite of power. You can practice finding powers and roots using the powers and roots worksheet.

## Constructing Equilateral Triangles

In this article you will learn to construct equilateral triangles. In geometry, a triangle is said to be an equilateral triangle if all three sides are equal and all three angles are congruent. You will learn to construct equilateral triangles using different methods with solved examples and practice questions.

## Learn to identify Congruent Angles and Triangles

In this article you will learn about congruent angles and triangles. In geometry, two shapes are said to be congruent if their corresponding characteristics are the same. You will learn to identify congruent angles and triangles using solved examples and practice questions.

## Understanding Polygons

In this article you will learn what are polygons. Polygons having all sides equal and all angles equal are called regular polygons. You will learn to calculate the interior and exterior angles of a polygon using solved examples and practice questions.

## The Pythagoras theorem

In this article you will learn about the Pythagoras theorem. This fundamental theorem in geometry states that the square of the hypotenuse of a right angled triangle is equal to the sum of the squares of the other two sides. You will learn to calculate hypotenuse of a triangle using the pythagoras theorem with solved examples and practice questions

## Learn about Pi the number

In this article you will learn about Pi the number. The number Pi is also called the Archimedes constant. It is a mathematical constant and is defined as the ratio of a circle’s circumference to its diameter. You will also learn what is pi math with solved examples.
