What I've learned from Ch. 10

           I've learned many things from chapter 10 in geometry. I learned the difference between a minor arc, major arc, and a semicircle. If an angle is inscribed in a circle, then the measure of the angle equals 1/2 the measure of its intercepted arc. I also learned that if a line is perpendicular to a radius of a circle at its endpoint on the circle, then the line is tangent to the circle. Lastly, I learned that a line that intersects a circle in exactly two points is called a secant.

Some careers that use these concepts are photography and astronomy.

How can you tell if an angle is inscribed?
