The hypotenuse of a right angle triangle is 10 cm and radius of its inscribed circle is 1 cm. Therefore, perimeter of the triangle is :

Explanation

With the given details, we can create a diagram.

Please refer to video for the diagram.

From the figure, incircle touches the circle at point `E,F and G`.
Also, length of tangent from any common point outside a circle are always equal.

`:. GC = FC = 10-x`

`AE = AG =x`

`BE = BF =1`

Now, parameter of given triangle `ABC = AB+BC+AC`
