Question

When a line is drawn parallel to a given line through a point not lying on the line, using ruler and compass, two arcs are drawn , one on the line and other at the point. If one of the arcs is of the radius 3 cm from the respective centre, the measure of other arc will be:

Solution

The correct option is B 3 cm
The measure of the other arc will be the same of radius 3 cm because we need to construct equal alternate angles.
