D&T ?

Chop off a corner?

Need a plane!

Only a little bit left

What about this cut?

What’s left?

The unkindest cut?

Going round the bend Overall Length (mm)4317 Overall Width (mm)1742 Overall Height (mm)1684 Wheelbase (mm)2694 Front track (mm)1470 Rear track (mm)1487 Turning circle (Corner- to-corner) (mm) Turning circle (Wall- to-wall) (mm) 11200

Are the front wheels parallel?

Trapezium does the trick

Ackerman’s answer

But will it scrub the tyres?

The Atomium – what shape?

Which compound, what formula?

Go on, play with me!

Maths KS3 Ma3 - symmetry

Is this a plane of symmetry?

Here’s one diagonal

Is the other diagonal equal?

How many diagonals like this?

And like this?

Did you get all these?

How many planes like this?

And like this?

Here are 2 joining green edges

And the third: the edge bisector

So how many planes of symmetry does a cube have?

Dots at the centres of each face

What shape do they make?

Looks familiar?

Well, that’s another story!

And a recent discovery!
