Question

Why we cannot construct a triangle of given sides as 5cm,5cm and 10cm?

Answer 1

For a triangle to be construct, the sun of two sides of a triangle must be greater than the third side but in this case, sum of two sides- 5cm+5cm = 10cm but not greater than 10cm. So, the triangle cannot be constructed.

Hope you got it?

Answer 2

The basic rule for constructing a triangle is sum of first and second side should be greater than third side.
5cm+5cm>10cm
But 10cm = 10cm Hence it is not greater than 10cm
So triangle cannot be constructed.
