Question

A line PQ=11.7cm is perpendicular to line QR.By using line QR,divide line PQ into 10 equal parts

Answer 1

just mark off any distance x on QR and measure it off 10 times. Let the last point marked be R.

Draw line PR. Then construct parallel lines at each marked point on QR, and their intersections with PQ will divide it into 10 equal segments.
