1. Measure your shoe and pick a starting point. Call it A.
• From A, the start point, choose a second point B and measure the distance by placing one foot directly in front of the other and counting "feet." You may need to estimate with decimals or fractions.
• From B, choose a third point C and measure the distance from B to C in the same way. C cannot be A and the line from B to C cannot be perpendicular to the line from A to B.
• Measure the distance from C to A in the same way.
• Write the three distances in the box.
• Determine the angle measure of the angle whose vertex is at B and is between the line connecting A and B and the line connecting B and C.
