four sided shapes facts

 

A square is a polygon with 4 sides of equal length and 4 right angle corners (90 degree corners). Because it has 4 sides of equal length, a square is a regular quadrilateral. A square is also a rectangle with equal sides and a rhombus with right angles.

A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. Thus, a rectangle has 4 angles, each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel.

A trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs. A trapezium can also have parallel legs.

A Rhombus is a flat shape with 4 equal straight sides. Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram). And the diagonals "p" and "q" of a rhombus bisect each other at right angles.

is there any four sided shapes you know other then these??

basic mathematical shapes

here are some basic math shapes. 

Circle 

A circle is a round, two dimensional shape that looks similar to the letter 'O'. In strict mathematical language, circle refers to the boundary of the shape while 'disk' is used to refer to the whole shape, including the inside. A straight line from the center of a circle to the edge is called the radius. https://www.kidsmathgamesonline.com

Pentagon

A pentagon is a 5 sided polygon with interior angles that add to 540 degrees. Regular pentagons have sides of equal length and interior angles of 108 degrees.  https://www.kidsmathgamesonline.com

Triangle 

The sum of all the internal angles of a triangle is always 180o no matter how the triangle is constructed.A triangle can always be split into two right triangles no matter how the triangle is constructed. https://www.smartconversion.com A triangle has 3 sides and 3 angles.

Octagon

An octagon has 8 exterior angles. The sum of the exterior angles of an octagon is 360°. Regular octagon: An octagon in which all sides and angles are equal. Each angle of a regular octagon is 135°.

Square

a square is a shape with four sides that are equal to each other and four 90 degrees angles.

Hexagon

A hexagon is a polygon with 6 sides and 6 corners (vertices). Like regular triangles and squares, hexagons fit together without gaps, which are known as tesselations. They therefore are often used for tiling floors. They are also quite common in nature. https://kids.kiddle.co

over all can crusher

 This year i have been working on a project called the can crusher this project i started this in February and finished it around June. here are some photos of my can crusher completed.

I was pretty happy how it turned out but I do think I could of done my welds way better and took bit more care into them but they are strong and working well. Something I really liked about doing this project was the knowledge I gained from doing this I learnt measurements are very important to get right and not to rush your work and take time to get better guilty. If I was to do this project again I would for sure take more time with it and spend more time on my welds.

  

engerning level 2 hand tools

 This year has been very good and i have been enjoying this year more then last.

here are some photo of my hand tools that i have used this year.

This is me with a file and fileing down my work. I am fileing one of my side rails for my can crusher 

this is after i cut out a piece of the rail.

This is me cutting with some tin snips. I was cutting some material for my can crusher. 

this is me using a hammer as i need to bend back my work because i didn't measure it straight and it wouldn't fit in my work but once i tried again i got it to fit.

                this is me using a hacksaw i am cutting a peace of metal for my handle of the can crusher.
