If an n-sided regular polygon is inscribed in a circle of radius r, as shown in the figure below, then n-isosceles triangles fill the circle. Based on the statement and figure above answer the following: 1. Express h and the base b of the isosceles triangle shown in terms of 9 and r. 2. Express the area of the isosceles triangle in terms of 9 and r. Use trig identities as needed. 3. Describe what happens as n goes to infinity, (notice the polygon fills the circle, the angle 6 goes to zero) 4. Use special limit rules to discuss your response, you may use any graphing tool to support your response
