Kia ora, this week for maths we have been working on angles.
Task 1) Pick a flag and investigate some of the following:-
You may like to draw this out on paper or put in on a google drawing. If you’d like it printed, email it to me before Morning Tea.
What shapes can you see in it?
There is a cross, two very stretched wide triangles and then two other triangles on the left and right.
Can you describe them and their angles?
The cross is more stretched width ways then length. The triangles at the top and the bottom are also stretched more width ways. Then there are also those two triangles on the side that are almost symmetrical but one point is just a smidge more longer than the others.
Does the flag have any lines of reflective symmetry, if so how many lines?
There is a lot of symmetry in this flag from to bottom and even from left to right. Both the black and the green triangles reflect again on the opposite direction.
Can you find any pairs of parallel lines? If so mark them on your flag.
There are some lines parallel to each other but they’re on an angle. Here they are:
It is where I put the white lines
Are there any lines perpendicular to one another?
No, not that I can tell.
Task 2)
On a doc/drawing or slide collate a range of pictures showing angles in the real world - think creatively they are literally everywhere!
