Draw a line segment AB of length 8 cm.At A and B , draw perpendiculars to AB using compasses and
ruler. Are the lines parallel to each other?
plz tell
Answers
Answer:
Step I: Take a convenient radius with A as centre and draw an arc intersecting the line at points W and X.
Step II: With W and X as centres and radius greater than AW, construct two arcs intersecting each other at M.
Step III: Join AM and extend it in both directions to P and Q.
Step IV: Take a convenient radius with B as centre and draw an arc intersecting the line at points Y and Z.
Step V: With Y and Z as centres and a radius greater than YB, construct two arcs intersecting each other at N.
Step VI: Join BN and extend it in both directions to S and R.
Let the lines perpendicular at A and B be PQ and RS, respectively.
Since, ∠QAB=90
°
and ∠ABR=90
°
Therefore, ∠QAB=∠ABR
When two parallel lines are intersected by a third line, the two alternate interior angles are equal.
Since, ∠QAB=∠ABR
Therefore, PQ and RS are parallel.
