5.1 Polygon Sum Conjecture (Interior Angle Sum)

5.1 Polygon Sum Conjecture powerpoint

5.2 Polygon Sum Conjecture pdf

 

In this lesson you will

 

● Discover a formula for finding the sum of the angle measures for any polygon

● Use deductive reasoning to explain why the polygon sum formula works

Triangles come in many different shapes and sizes.

However, as you discovered in Chapter 4, the sum of the angle measures of any triangle is 180°.

In this lesson you will investigate the sum of the angle measures of other polygons.

After you find a pattern, you’ll write a formula that relates the number of sides

of a polygon to the sum of the measures of its angles.
