Question

If a is parallel to c, then ________.

t $⊥$ a
b $⊥$ c
a || b || c
b || t

hint Hint:

In this question we have to chose the correct statement from the given options. as $angle$ XPB and $angle$ APQ are equal as both are vertically opposite angles and as the sum of $angle$ APQ and $angle$ QRE is 180 $times$ so they both are alternate interior angles which make a parallel to b. Now a is parallel to b and is also parallel to c , so b is parallel to c.

The correct answer is: a || b || c

If a is parallel to c, then _ $a parallel to b parallel to c$ ___.
