![]() ![]() Assume that segments that appear to be tangent are tangent. x-15 Take the positive square root of each side. Use the Pythagorean Theorem with right ABC (AB)+(BC)? - (AC)? Pythagorean Theorem x2 +82 - 172 Substitution x2+64 -289 Simply x2 = 225 Subtract 64 from each side. CD is a radius, so CD-8 and AC-9+8 or 17. 18 is tangent to OC, AB is perpendicular to radius C. If two segments from the same exterior point are tangent to a circle, then they are congruent. A line is tangent to a circle if and only if it is perpendicular to a radius at a point of tangency. ![]() A common tangent is a line rayos segment that is tangent to two circles in the same plane.
