Tangent and radius theorem
WebSOLUTION According to Theorem 6.2, the tangent determining the line of sight and the radius of the moon form a right angle. In the right triangle determined, let t represent the desired distance. Using the Pythagorean Theorem, A consequence of Theorem 6.2 is Corollary 6.2, which has three possible cases. WebIn particular, it uses the Pythagorean Theorem and a proof by contradiction to establish that the tangent line and radius meet perpendicularly. The teacher may wish to go over the …

[EDIT] OK some more hints: Let's say R is the radius, and (xr, yr) is on the circle, and (xc, yc ... WebA tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The angles in a triangle add up to 180, so ∠BCA + ∠OAC + y = 180 …
