If the inversion of a point A(3,4) with respect to a circle having centre as origin is A'(12,16) , find the diameter of the circle. also find the inversion point of B(6,8) with respect to the circle.

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

I’m stuck on this equation, anyone got the answer?

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?
