(a)
Using a ruler and a pair of compasses only
(i)
construct triangle ABC such that |AB| = 9 cm, angle BAC = 60° and angle ABC = 45°.
(ii)
construct a line from the point C perpendicular to line AB and let it meet AB at P. Measure |CP| and |AP|
(b)
What is the value of angle ACP?
(a)
Mansah earns a salary of ₵10,000.00 per month as a sales girl. In addition to the salary, she is given a commission of 1.5% of whatever sales she makes in a month. In January this year, she made sales of ₵7,500,000.00. What was the total amount Mansah earned at the end of January?
(b)

(b)
On the graph sheet, mark the x-axis from –5 to 5 and the y-axis from –6 to 6
(c)
(i)
Plot on the same graph sheet the points A(1, 1
(ii)
Join the points to form a triangle. What type of triangle have you drawn?
(d)
Draw the image triangle A1B1C1 of ABC under a reflection in the y-axis, where A→A1, B→B1 and C→C1. Label the vertices and the co-ordinates clearly.
(e)
Draw the image triangle A2B2C2 of triangle ABC under an enlargement with scale factor –1 with the centre of enlargement as the origin (0,0), where A→A2, B→B2 and C→C2. Show all lines of enlargement. Label the vertices and co-ordinates clearly
(f)
What single transformation maps A1B1C1 onto A2B2C2 where A1→A2, B1→ B2 and C1→C2?
(a)
