Question

I’m the diagram below, C is the midpoint of AB. If AC is 4 centimeters, what is the length of CBA.4cmB.8cmC.6cmD.2cm

Answer 1

Consider that a mid-point is at equal distances from each end of the line segment.

Given that C is the mid point of AB, so point C must be at equal distance from ends A and B,

$AC=CB$

Given that AC measures 4 centimeters,

$AC=4\text{ cm}$

Substitute the value,

$CB=4\text{ cm}$

Therefore, option A is the correct choice.
