a line is a tangent to a circle if it touches it superficially once but doesn't cross it.
Answer
For triangle XYZ we can identify three segments that touch the circle but don't cross it, like this:
Similarly, for triangle ABC:
Summary
• Segments that are tangent to circle w in XYZ: XY, YZ and ZX
,
• Segments that are tangent to circle D in ABC: AB, BC and CA
