One can use the area formula for triangles to evaluate the area of an n sided regular polygon of side length c. One can construct n sub-triangles having the sides c and a=b=c/[2 cos(π/2-π/n)]. The area of this sub-triangle is (c2/4)cot(π/n),so that the area of the polygon becomes- 4tan() 2 n c n Area π =

What is the length of that side? It is 5, so I will replace the “o” in the formula with 5. sin𝐴=5 ℎ We don’t know the length of the hypotenuse, so it will be “x.” sin𝐴=5 𝑥 So here is the tricky part. This side of the equation means the “sine of the angle.” Our angle is 30°, so let’s replace that side with sin30°.

1. A triangle can be formed using the following sets of lengths: 3, 5, 6 5, 6, 9 2. The set consisting of 3, 6, and 9 did not form a triangle. 3+6=9 3. The sum of the lengths of any two sides of a triangle is greater than the length of the third side. This exploration leads to the following theorem: Example 1.
