Circle Properties Practice Test

Understanding radii and chords: Jenna measures a circle on a map symbol. She draws a radius from the center to the edge and then draws a chord between two edge points. She learns that the diameter is a chord that goes through the center. A chord can be shorter than the diameter. What is the relationship between the radius and a chord of a circle?

Real-life applications: A designer makes a circular window. The radius is measured from the center to the glass edge, and the diameter is twice that length. A chord is any straight segment connecting two points on the window’s edge. The diameter is a special chord through the center. Which statement about the radius and chord of a circle is true?
