Step 1 Mark a point on your paper.

Step 2 Place the needle of the compass on that point and draw a circle. Make sure the whole circle fits on your piece of paper.

Step 3 Keep the compass setting. Mark a point on the circle. Label this point A. Then place the needle of the compass on that point, and draw an arc that intersects the circle. Mark that intersection point (but don't label it).

Step 4 Keep the compass setting. Place the needle of the compass on that new unlabeled point, and draw an arc that intersects the circle. Label the intersection point with the circle as point B.

Step 5 Keep the compass setting. Place the needle of the compass on point B, and draw an arc that intersects the circle. Mark that intersection (but don't label it).

Step 6 Keep the compass setting. Place the needle of the compass on that new unlabeled point, and draw an arc that intersects the circle. Label the intersection point with the circle as point C.

Step 7 Use a straightedge to draw segments AB, BC, and CA

Step 8 You should now have an equilateral triangle, ?ABC.

Check your work by using a protractor to verify that m∠A = m∠B =m∠C =60?.

Check your work by using a ruler to verify that AB = BC = CA.
