It was a dull Monday afternoon and I was in a dissecting mood. Using different colours I split each of the outlines below into 3 congruent shapes.
Your challenge is to work out how I did it (click the help tab above for more).

Numeracy"Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

Go MathsLearning 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. Maths MapAre you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic. | ||

Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.
See the National Curriculum page for links to related online activities and resources.
Click a paint tin then click a square in one of the outlines to change its colour.
Your objective is to split the area inside the outline into a number of congruent shapes. So, for example if this is the outline given:
The congruent shapes could be shown using the colours like this:
Notice that each of the coloured shapes are congruent.
For each outline there may be a number of different ways to fill it with congruent shapes. You need to find the way I did it to be marked correct. You can have as many different attempts as you want (use the clear button to start again). The colours don't matter, you do not need to choose the same colours as I did. It is just the shapes that need to be correct.
You can learn more about the concept of congruent shapes by doing the Congruent Triangles exercise.
