Question

Can you construct a triangle that has side lengths 2 yd, 9 yd, and 10 yd?

Answer 1

Yes

The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.

This happens for all possible couples in your case:

`2+9=11>10`

`2+10=12>9`

`9+10=19>2`
