Chapter 10.4, Problem 19P
Use the idea of walking and turning around a shape to determine the sum of the exterior angles of the quadrilateral in Figure 10.93 . In other words. Determine e + f + g + h . Measure with a protractor to check that your formula is correct for this quadrilateral.
Figure 10.93 A quadrilateral
- Will there be a similar formula for the sum of the exterior angles of pentagons, hexagons, 7-gons (also known as heptagons), octagons, and so on? Explain.
- Using your formula for the sum of the exterior angles of a quadrilateral, deduce the sum of the interior angles of the quadrilateral. In other words. find a + b + c + d, as pictured in Figure 10.93 . Explain your reasoning. Measure with a protractor to verify that your formula is correct for this quadrilateral.
- Based on your work, what formula would you expect to be true for the sum of the interior angles of a pentagon? What about for hexagons? What about for a
polygon with n sides? Explain briefly
