Question

true or false? the blue radius is perpendicular to the green chord.
a. true
b. false

Explanation:

Step1: Recall circle - chord property

A radius of a circle that is perpendicular to a chord bisects the chord.

Step2: Analyze given lengths

The two segments of the chord are of equal length (both 7.2), which implies the radius bisects the chord.

Step3: Determine perpendicularity

If a radius bisects a chord, then it is perpendicular to the chord.

Answer:

A. True
