List the five steps used to sketch a circle.
What will be an ideal response?
STEP 1 Lay out the vertical and horizontal center lines in the correct location. Measure off half the diameter of the circle on each side of the two center lines.
STEP 2 Lightly draw two vertical and two horizontal lines passing through the points marked off on the center lines. These lines, properly drawn, will be parallel and will form a square.
STEP 3 Draw diagonal lines from each corner of the square to form four triangles.
STEP 4 Place a dot in the center of each triangle through which an arc is to pass.
STEP 5 Sketch the arc for one quarter of the circle. Start at one center line and draw the arc through the dot to the next center line. Continue until the circle is complete. Darken the circle and erase all the guide lines to simplify the reading of the sketch.
