Question

Two sides of an isosceles triangle have lengths of 4 and 8. What is the length of the third side?A. 4B. 6C. 8D. 12

Answer 1

SOLUTION:

An isosceles triangle has two sides equal. Thus, this isosceles triangle would either have for a third side 4 or 8.

Using the triangle inequality, however, we can rule out 4. This is because;

$4+4=8$

Therefore, we have no triangle;

Therefore, the answer is;

$8$
