To learn more about decagons, review the accompanying lesson called Decagon: Definition & Shape. You will learn how to: Explain which shapes qualify as polygons Compare and contrast concave and convex decagons Draw simple and complex decagons ...
One method is to draw two chords, and then draw the perpendicular bisectors of the chords.2 These bisectors cross at the center of the circle, as seen in Figure 3. 2 The perpendicular bisector of a line is obtained by drawing two circles centered at the ends of the line and having a ...
1. Given an arbitrary point , draw a circle centered on and a diameter drawn through . 2. Call the right end of the diameter dividing the circle into a semicircle . 3. Construct the diameter perpendicular to the original diameter by finding the perpendicular bisector . 4. Construct a ...
