Math Problem Statement

Celestina constructed a circle with center C and radius DC. She then constructed chord AB to be perpendicular to radius DC at point E. She measured segment AE to be 8 inches. Identify the length of segment BE.

Solution

In the image, we see a circle with center CC and radius DCDC. Chord ABAB is constructed such that it is perpendicular to radius DCDC at point EE, and the length of segment AEAE is given as 8 inches.

To find the length of segment BEBE, we can use the fact that the perpendicular from the center of a circle to a chord bisects the chord. Since AE=8AE = 8, it follows that BE=AEBE = AE, because the perpendicular bisects the chord into two equal segments.

Thus, BE=8BE = 8 inches.

So, the correct answer is:

  • Segment BE is 8 inches.

Here are some additional related questions you may find helpful:

  1. Why is the perpendicular from the center of a circle to a chord always bisecting the chord?
  2. How does the Pythagorean theorem apply in this case, and where would it be used?
  3. Can you solve for the radius of the circle if we were given a different set of measurements?
  4. How do we calculate the length of a chord in a circle if we know the radius and perpendicular distance from the center to the chord?
  5. What properties do we use in solving problems with perpendiculars drawn to chords?

Tip: Always look for symmetry in geometry problems involving circles. The perpendicular from the center to a chord often creates equal segments.
