SMX Math Help
Same job as HELP on the control. Pick the case that matches the print. The control has no type 21.

10Intersection of two linesTwo lines, four points — where they cross11Intersection of two lines from an angleTwo lines and the angle between them12Line intersection with a tangent radiusTwo lines with a blend radius on the cornerB · Line–arc13–14
13Line and arc, centre knownLine cutting a circle, centre known14Line and arc, centre not givenLine cutting an arc, centre not givenC · Arc–arc15
15Two arcsTwo circles — both crossing pointsD · Tangency16–19
16Line tangent to two arcs, line does not pass between the centresOutside tangent between two circles17Line tangent to one arcLine just touching one circle18Line tangent to two arcs, line crosses between the centresCrossed tangent between two circles19Arc tangent to two arcsBlend radius tangent to two arcsE · Centres, points, radius20, 22–24, 27
