[Math 9] in 3 circles O1, O2, O3 pair a contact with each other in A, B, C
Lesson 1: For semicircle diameter AB. Two guys tangential Ax, By.Lay point of supply M AB (Other M point between supply AB). Ke tangent to the circle at the M cutting Ax, By now I, C is the intersection of Ax J.Goi with MB. D is the intersection of By and MA.CMR: CD, IJ, AB concurrent. Lesson 2: For 3 circles O1, O2, O3 pair a contact with each other in A, B, CA of (O1) and (O2), B of (O2) and (O3), C in (O1) and ( O3). E is the intersection of AC and (O3). F is the intersection of AB and (O3). CMR: 3 points E, F; O3 center of the circle line! Help yourselves you!!
