a circle construct the mini-mum chord. Ex. 435. If two chords are drawn from one extremity of a diameter,making unequal angles with it, the chords are unequal. Ex. 436. The perpendicular from the center of a circle to a side ofan inscribed equilateral triangle is less than the perpendicular from… … A M T B Given line AB, tangent to circle 0 at r, and OT, a radius drawnto the point of tangency.To prove AB ± OT. Argument 1. Let M be any point on AB other than T; then M is outside the circumference. 2. Draw OM, intersecting the circumference at S, 3. OS < OM, 4. OS = OT, 5. .-. OT < OM..…
