7. When two circles are tangent, draw the co mmon tangent line or connect the centers AB=O_1 C AB⊥O_1 C AB⊥O_2 B O_1O_2=r_1+r_2 O_2C=r_2-r_1 △O_1CO_2isan ght triangle O_1C=√((r_2+r_1)^2-(r_2-r_1)^2)A B is the common tangent line. r and r,...
In this way, you can differentiate between the pickbox and the crosshair. At the end of this video, I will explain how to customize the pickbox and crosshair. So come let's focus on polygon again. As I select the polygon here I have to specify the sides and I am typing it as 4 ...
pleaseselectthe left most circle andchange colourto yellow. Thenconnectthe two circles to the bottom (r="10.35" and r="10.5") with all possibletangents,cut their lengthto theorthogonal projectionof the next near circles' center. Keep one of the projection lines as dash-dotted line with line...
