Question

Which of the following represent incorrect relationship?

• A. AB = 2AC
• B. BC = AC
• C. AB = 2BC
• D. $AB=\frac{AC}{2}$

Answer 1

The correct option is D $AB=\frac{AC}{2}$

$\to$Radius of circle is distance between centre and circumference of the circle.
Hence, AC = BC
Option (b) is correct.

$\to$ Diameter of a circle is twice the radius of the circle.
Hence, AB = 2AC = 2BC
Option (a) and (c) are correct.

Option (d) is incorrect.
