Question

sc1 q2: construct a line perpendicular to the black line that goes through point g. use the angle measuring tool to check that you have constructed a perpendicular line.

Explanation:

Step1: Place compass on point G

Set the compass width to an appropriate length.

Step2: Draw arcs intersecting black line

Draw two arcs that cross the black - line at two distinct points, say A and B.

Step3: Set compass on A and B

With the same compass width, draw arcs above and below the black line from points A and B respectively. Let these arcs intersect at points C and D.

Step4: Draw line through C and D

The line CD is perpendicular to the black line and passes through point G. You can use the angle - measuring tool to verify that the angle between the black line and the constructed line is 90 degrees.

Answer:

The constructed line CD passing through point G and perpendicular to the black line.
