प्रश्न
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
उत्तर
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°
