• At q using a protractor mark and draw an angle of 52o.
• At r mark and draw an angle of 46o
• Mark the point of intersection of the two angles.
• This is the point p.

• Draw a line segment 12cm in length. Name the points and mark the length.
• Use a protractor to draw a line at 65o to |ab|.
• Use a compass with a as centre and 9cm radius to draw an arc on this line.
• Mark the point of intersection c.
• Join c to b and complete labels.

Draw the angle aob. Using the vertex o as centre draw an arc to meet the arms of the angle at
x and y. Using x as centre and the same radius draw a new arc. Using y as centre and the same radius draw an overlapping arc. Mark the point where the arcs meet. The bisector is the line from o to this point.
