Line a is parallel to line b line C is perpendicular to line b line C forms a 60 degree angle with line a why is this figure impossible to draw?

Question

Find out why this figure cannot be drawn on paper.

Answer 1

If line a is parallel to line b and line C is perpendicular to line b

then line C must also be perpendicular to line a.  This means

that line C forms an 90 degree angle with line a... NOT 60 degrees.
