Question

One side of a triangle measures 10 inches. Which could be the measures of the other 2 sides of the triangle?

A. 3 in & 8 in
B. 4 in & 6 in
C. 5 in & 15 in
D. 6 in & 18 in

Answer 1

B. 4 and 6 in

Explanation:

The triangle inequality rule states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.

So for the first qualification, we can eliminate A, C, and D. Therefore the answer is B, 4 & 6 in
