Deck 35: Sketching Curved Lines and Circles

Question 1

List the five steps in sketching an arc.

Answer 1

When an arc must be drawn so that it connects two straight lines (in other words, is tangent to them), it may be sketched easily if five basic steps are followed. STEP 1 Extend the straight lines so they intersect. STEP 2 Step off the same distance from the intersection (center) of both lines. STEP 3 Draw the diagonal line through these two points to form a triangle. STEP 4 Place a dot in the center of the triangle. STEP 5 Start at one of the lines and sketch an arc that runs through the dot and ends on the other line. Darken the arc and erase all unnecessary lines.

Question 2

The accompanying figure illustrates the steps for drawing an arc. Describe step 4.

Answer 2

In STEP 4, one places a dot in the center of the triangle.

Question 3

The accompanying figure illustrates the steps for drawing an arc. Describe step 3.

Answer 3

In STEP 3, one draws the diagonal line through these two points to form a triangle.

Question 4

When an arc must be drawn so that it connects two straight lines, in other words it is ____ to them.
