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 […]
Read More →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 […]
Read More →What is an Angle Angles are formed by two rays or lines called the arms or sides of the angle, sharing a common endpoint, called the vertex of the angle. Types of angles There are various types of angles. The angles can be classified into two main types. Basis on their measure or magnitude. Based […]
Read More →Perpendicular Lines Definition: Perpendicular Lines A line intersect another line and the angle between them is a right angle or 900 then the lines are said to be “Perpendicular.” If a line AB perpendicular to CD, we write asAB ⊥ CD. Perpendicular denoted by “⊥” If one of the angles formed by the intersection of two lines or line segments […]

The symbol “∥” is used to denote parallel lines. Example- PQ ∥ RS denoted that line PQ parallel to line RS. Intersecting lines […]

Pythagoras theorem applies to right triangles and states that, The square on the hypotenuse is equal to the sum of the squares on the other two sides. (hypotenuse)2 = (Base)2+(Perpendicular)2 […]
