Flags To Look Into
There are lots of flags that were involed in history. I will be focusing on flags in world war 2. This is one of the first flags I will show you. Also, this is when world war 2 began. Any way, this flag has a irregular dodecagon.mIt has 6 pairs of parallel sides. It has rotation symmetry. Each time you turn it 90*, it will show how it has turn symmetry. It also has mirror symmetry. It can be folded 2 times, and have symmetry. Also, this flag has two trapazoids. Trapaziods are quadralaterals, . . -
Flags 2
and the trapaziods have 1 set of parallel sides. Also, the flag has 2 parallelagrams. These shapes are also quadralaterals. They have 2 pairs of parallel sides. Now, the German flag. The German flag is three different rectangles, each a different color, stacked on top of each other. The flag was a black, red and yellow rectangles. Rectangles are parallelograms. Also, each angle is 90*. -
Flags 3
The Japanese flag was a white rectangle, and then in the center was a red circle.The circle is not a polygon, for it has rounded sides, which breaks one of the rules of polygons.Rectangles are polygons, 90 for each angle, parallelogram. -
Flags 4
The American flag has 14 rectangles, than 50 irregular decagons. Decagons have a angle measure of 1,440*. Rectangles are polygons, 90 for each angle, parallelogram. -
British Radar Systems
The radars that the British used to send planes to intercept the Luftwaffe would be large triangles, with smaller triangles at different points on the larger triangle. The larger triangle was a isosceles triangle, irregular polygon. It has 180 for a sum, and it is a polygon. The smaller triangles on it are also polygons, and have a total sum of 180. The triangles are scalene triangles, irregular polygon and there are three on each side. -
Plans For Battle
(Not picture used)Also, on plans for battles, ships and landing spots might be a rectangle. Rectangles are polygons, 90 for each angle, parallelogram. The X's in them were polygons, for they were dark. They were irregular polygons, and had 12 sides. Also, the arrows could be a polygon, but some had curves. When they didn't have curves, they would be an irregular polygon, and a heptagon. -
6 Years Of Fighting
World War 2 took place 1939-1945. That was 6 years, and a regular hexagon has six sides and tiles. -

World war 2 was 1939-1945. That was 6 years, and a hexagon has 6 sides, and when its regular, it tiles. -
British Radars 2
The radars that the British used to send planes to intercept the Luftwaffe were circular shapes and were mounted on a small triangle with wires in it, that sent messages to the British. The circle is not a polygon, for it has rounded sides, which breaks one of the rules of polygons. Also, ww2 was six years long, and a hexagon has six sides. -

Designs And Shapes Today
No Description -
Shapes Have Been Taught
We began shapes and designs, and learned about the triangles, and we sorted shapes into groups. We also began work on our tesselation. Tessellation is when you put one or more shapes next to each other over and over again, and if each vertex has 360*, then the shape or shapes will tessellate. Also, all the vertexes have to be 360*. -
Angles
Today, we began learning about angles. We learned about how before navagation systems were at their best, you could be 9* off and miss your destanation completly. Also, we learned about tranversals, and how if we know one angle, we can find the other. -
Sums And Angles
Now, we learned about the angle sum of triangles, then squares, and then a bunch of other shapes. Also, we learned about exterior angles. -
The Building Stuff
In these lessons, we learned that the two smaller sides of a shape have to have their lengths have a sum larger than the longest side, or it will not make a shape. Now, I have some questions for you. What war did I relate this unit to? What must the length of the two smaller sides of a triangles be? LAST MINUTE FUN FACT! A tranversal is a line or line segment that cuts through lines, shapes or line segments. Now, please don't ask How long did this project take you? Now, i am ready for questions
