Level 1 Level 2 Description More Construction

This is level 1; Construct the diagrams using a ruler and pair of compasses. Give your answers in centimetres to one decimal place.

1. At the top of a page draw a horizontal straight line, AB, 13cm long.
Point C lies on this line exactly 6cm from the point A.
Draw the point D further down the page such that AD is 12cm
and BD is 11cm.
Measure the distance CD.

cm Correct Wrong

2. In the centre of a page draw a vertical line, AC, that is 15cm long.
DB is the perpendicular bisector of AC and AC is the perpendicular bisector of DB.
DB is 13cm long.
Measure the length of one side of rhombus ABCD.

cm Correct Wrong

3. Draw triangle ABC such that:
AB is 10.7cm, BC is 12.8cm and CA is 13cm.
Use compasses and ruler to bisect the angle BÂC and extend this bisector until it reaches line BC at point D.
Measure the distance CD.

cm Correct Wrong

4. Draw the perpendicular bisector of a 12.6cm horizontal line and use it to draw an isoceles triangle of height 11.3cm.
What is the length of either of the two sloping sides of the triangle.

cm Correct Wrong

5. XY is the diameter of a semicircle. XY is of length 13.7cm.
The point Z lies on the curved side of the semicircle such that XZ is 7.8cm.
What is the distance from Z to Y?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
