Question

Circle C with chord DE perpendicular to
diameter AB is shown.
What is the length of FE?

Answer 1

`FE=5\ units`

Explanation:

we know that

If a diameter of a circle is perpendicular to a chord, then it bisects the chord

In this problem

AB is a diameter of circle C

The chord DE is perpendicular to the diameter AB

so

AB bisects the chord DE

That means

FD=FE

we have

`FD=5\ units`

therefore

`FE=5\ units`
