Inscribed angle - In geometry, an inscribed angle is formed when two secant lines of a circle (or, in a degenerate case, when one secant line and one tangent line of that circle) intersect on the circle. Typically, it is easiest to think of an inscribed angle as being defined by two chords of the circle..

Inscribed Angles in a Circle Subtended by the Same Chord demonstrations.wolfram.com The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. All angles inscribed in a circle and subtended by the same chord are equal. The inscribed angle is equal to one half of the central angle subtended by the chord. Contributed by: Michael Schreiber
Question : a) Find the Formula for the Area 'An' of the regular polygon with n sides inscribed in a circle of radius 1. Express your answer as a trigonometric function of n.
b) Find A3, A4, A100, and A1000, correct to six decimal places. What do the values get closer and closer to? Why?
-There are diagrams included, A3 is shown as a circle with a regular triangle inscribed in it, A4 is a circle with a regular Square inscribed in it, A5 is a circle with a regular pentagon, and so on.

Answer : Here's what you do: Take any regular polygon and draw a line connecting a corner and the center of the circle. Since the polygon is inscribed, that line is a radius (of length one, as stipulated in the problem). You'll notice that the polygon is now broken up into n triangles going around the circle (for example, in a hexagon, you will have connected the diagonals and broken the hexagon into triangles of 60 ). These triangles will all have two sides of lengths 1 (since they are radii) and will have an angle of 360/n (since the angles form a full 360 together and each one is the same, they must all have this measurement). Using the formula for the area of a triangle, you have: Area of a triangle = (1/2)1 * 1 * sin(360/n) = (1/2)sin(360/n) Since you have n triangles, you have An = n/2*sin(360/n) (or n/2 * sin(2 /n) in radians). For b, just plug 3, 4, 100 and 1000 into this. For A3 you should get (3 3)/4 and for A4 you should get 2. Looking at the picture, yo..

Question : I have a scalene triangle and I'm trying to inscribe it into a circle (draw a circle around it.) How do I do that...
BTW: It's constructions so there aren't any angle or length measurements...
Thanks for the help!
Answer : draw bisector of each side the triangle and the point of their intersection will be the center of the circle. So place the pointer at that point and take the radius as the distance from that centre to anyone vertex of the triangle and draw the circle.
