5 7 The figure shows the first few stages of a fractal. Stage 0 begins with a segment. Then, in the next stage, two shorter perpendicular segments are added on at the end of the segment. With each successive stage, two additional shorter segments are added to the segments added in the prior stage. How many new segments would be added at Stage 4? A 8 B 6 C 3 D 3 8 The diagram shows a pattern of regular polygons with 3, 4, 5, and 6 sides. Inside each polygon, segments are drawn from the center to the vertices, forming congruent central angles in each polygon. What would be the measure of the central angle formed inside a regular decagon, which has 0 sides? Record your answer and fill in the bubbles on your answer document.
