Question

Can we draw a triangle for side lengths 5, 4, and 10 units? If so, mention the reason.

  1. No, as angles are not given
  2. No, as it does not follow triangle inequality
  3. Yes, as lengths are mentioned
  4. Yes, as it doesn’t follow the longer side theorem.

hintHint:

We know that according to triangle inequality theorem, In a triangle the sum of two sides should be greater than the third side. So to know whether we can draw a triangle from the given measurement we need to check the sum of two sides is greater than the third or not.

The correct answer is: No, as it does not follow triangle inequality


    We cannot draw the triangle as the sum of lengths of the two sides is not greater than the third side. It does not follow triangle inequality.
    APQ, the three sides are 5, 4 and 10 units.
    5+4=9less than10              5+10=15greater than4                 4+10=14greater than5
    So, we can not draw a triangle from the given measurement.
