Question

How many different triangles can you make that have side lengths of 5,10,and 20 inches

Answer 1

• None

-------------------------

According to Triangle Inequality Theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case:

• 5 + 10 = 15, which is less than the third side length 20.

Therefore, there are no triangles that can be made with these side lengths.
