c2 = a2 + b2
29^2 = a^2 + 20^2
841 = a^2 + 400
441 = a^2
a = 21

What is a triangle?

  • In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.
  • The important property of a triangle is that the sum of the internal angles of a triangle is equal to  180°(180 degrees).
  • This property is called the angle sum property of a triangle.

The right triangle is a special type of triangle. The angle between base and the perpendicular is always 90 degrees.

Using Pythagoras theorem:-

          (hypotenuse)²=(base)²+(perpendicular)²

          (29)²=(20)²+(perpendicular)²

         (perpendicular)²=(29)²-(20)²

           (perpendicular)²=841-400

           perpendicular= [tex]\sqrt{441}[/tex]

             perpendicular= 21 centimeteres
