Question

Draw a line segment AB = 6 cm. Mark two points P and Q on it. Draw lines
perpendicular to AB through P and Q (PR and QS), What can you say about PR and
QS? Are these parallel? Justify your answer.
​

Answer 1

Answer:

PR||QS

Step-by-step explanation:

if the corresponding angles,the angles

that are on the same corner at each intersection,are equal, then the lines are parallel the second is if the alternate interior angles, the angles that are on opposite sides of the transveral and inside the parallel lines,are equal,then the lines are parallel

APR=90°

BPR=90°

AQS=90°

BQS=90°

The corresponding angles=equal=90°

=>PR and QS are parallel

PR||QS

This is the answer
