Notice that all eight of the angles in the center of the pattern meet to form a circle. Let a° represent the measure of each pin
k central angle and b° represent the measure of each green central angle.
Which of the following equations are true? Select all that apply.
(1) 4a° = 180°
(2) 2b° = 90°
(3) 4a° + 4b° = 360°
(4) a° = 90° - b°
(5) 2(a° + b°) = 180°
