If an n-sided regular polygon is inscribed in a circle of radius r, as shown in the figure below, tl n-isosceles triangles fill the circle. Circle b. -Inscribed polygon Based on the statement and figure above answer the following: 1. Express hand the base b of the isosceles triangle shown in terms of e and r. 2. Express the area of the isosceles triangle in terms of e and r. Use trig identities as needed. 3. Describe what happens as n goes to infinity, (notice the polygon fills the circle, the angle e goes t zero)
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
