What is Meant by Right Triangle?

In Mathematics, a triangle is a polygon with three sides and three vertices. It is a closed polygon. Based on the sides and angles, a triangle can be classified into different types. A right triangle is one among them. In a right triangle, one of the angles is the right angle. It means that one of the angles measures 90 degrees. A right triangle is stated by Pythagoras theorem. It states that the square of the hypotenuse side is equal to the sum of the squares of the other two sides. If a (base), b (perpendicular), and c(hypotenuse) are the sides of the right triangle, the formula is given by

a2 + b2= c2
