Question

all pairs of parallel lines
pairs of intersecting lines
collinear points
concurrent lines and point of concurrence​

Answer 1

Question isn't clear but I kind of understand this... but olease next post a clear picture.

PARALLEL LINES: p||q and r||s.

INTERSCECTING LINES:

p intersect s at C

p intersects r at A

q intersect s at E

t interspect p at B

t intersects s at F

COLLINEAR POINTS

A and C on p

A and D on r

F, C and E on s

D and E on q

D, B and F on t

CONCURRENT LINES

Lines t, r and q are concurrent and they meet at D(point of concurrence).
