Question

what is the relationship between lines c and b?
a

b

c

d

c ? b

||

neither,
they are
skew lines

⊥

Explanation:

Step1: Identify the symbol

The diagram shows a right angle (square) at the intersection of lines \( c \) and \( b \).

Step2: Recall the definition of perpendicular lines

Perpendicular lines are lines that intersect at a right angle (90 degrees), and the symbol for perpendicular is \( \perp \).

Step3: Match with the options

The third option (the symbol \( \perp \)) represents perpendicular lines, which matches the right angle between \( c \) and \( b \).

Answer:

\( \perp \) (the third option with the perpendicular symbol)
