Study Notes
Circle with Center Z and Chords VW and XY
- The circle has center point Z and two chords: VW and XY.
- A line segment from the center point Z to the chord XY makes an obtuse angle.
- The distance from the center point Z to the chord XY is 15 units.
- A second line segment from the center point Z, perpendicular to chord VW, divides the chord VW into two equal parts of 20 units each.
Radius of Circle Z
- The radius of the circle (⊙Z) is unknown and needs to be found.
- The possible answers are: 25, 20, 15, or 10 units.
