Question

Find the correct order of length of sides in the following triangle.

• A. AB < AC < BC
• B. AB < BC < AC
• C. BC < AB < AC
• D. AB > AC > BC

Answer 1

The correct option is B AB < BC < AC


In any triangle, the side opposite to the larger (greater) angle is longer.

The ascending order of the angles in the triangle shown above is ${40}^{\circ }$, ${65}^{\circ }$, ${75}^{\circ }$.
So, sides in ascending order will be AB, BC, AC.

$\therefore$ the correct order is AB < BC < AC.
