Question

Draw a line segment AB = 7 cm and mark a point P on it. Draw a line perpendicular to the given line segment at P

Answer 1

Step 1: Draw a line AB = 7 cm and take a point P anywhere on the line.

Step 2: Place the set square on the line in such a way that the vertex which forms right angle coincides with P and one arm of the right angle coincides with the line AB.

Step 3: Draw a line PQ through P along the other arm of the right angle of the set square.

Step 4: The line PQ is perpendicular to the line AB at P.

That is, PQ ⊥ AB

∠APQ = ∠BPQ = 90°
