Question

The length of the hypotenuse in the figure is:

• A. A and B
• B. A and C
• C. B and A
• D. B and C

Answer 1

The correct option is B

A and C

Triangle ABC is a right angle triangle, right angled at B, so AC is the hypotenuse.
Therefore using distance formula,
$A{C}^2=(5-1{)}^2+(1-4{)}^2$
= 16 + 9
$A{C}^2=25$
$\therefore AC=5$
