Question

draw a line l and take a point P on it.Through P, draw a line segment PQ perpendicular to l.Now draw a perpendicular to PQ at Q (use ruler and compass)

Answer 1

First draw a line and take a point on it make 90 degree angle . make perpendicular....

Answer 2

Therefore, $PQ\perp I$ and $QR \perp PQ$

Step-by-step explanation:

Given,

Draw a line $I$ and take a point $P$ on it.Through $P$, draw a line where $PQ\perp I$.Now draw a perpendicular to $PQ$ at $Q$.

Following steps:

• Draw a line $I$
• Take a point $P$ on line $I$

• Take any measure and draw a curve with $P$ as a center which cuts line $I$ at $A$ and $B$
• From point $A$ and $C$ cuts on the curve like $C$ and $D$
• Draw two curve from point $C$ and $D$ which cuts at point $Q$
• Join $P$ and $Q$ where $PQ\perp I$
• Similarly, by the same process draw a perpendicular line $QR$ on $PQ$ as shown in figure.

Now, $PQ\perp I$ and $QR \perp PQ$
