Shapes homework and yes I am thick

[peasinapod]

Dont want to look a total idiot when I see DS teacher at pick up . Year 2 . I have asked her to explain home work as I would rather look silly than try and help him and get it wrong . the homework stems from a square not being a square any more . it still is IYSWIM but now its a different type of rectangle . (BORING ) So my question is can some one tell me the basic shapes and the rules as a square is four equal sides an oblong is ???? a rectangle is ????? do you see what I mean . I am not that thick really I just want to get it strait in my head . Thanks from one thick mum .

A square is a square not a rectangle. It has 4 equal sides. A rectangle has 2 pairs of equal and opposite sides. Although both have equal right angles. A rectangle is an oblong.

Apparently mine were told that a square is a special kind of rectangle..... (ie all sides the same length)

good god- a square is a special rectangle? how confused d theyb want our children to be?????????

whats the one that has two equal opposite straight sides and two equal diagonal sideslike this //? or am i barking????

A rectangle is a four sided shape with four right angles, opposite sides are of equal length.
A square is a rectangle, only all four sides are the same length.
And oblong is just another word for rectangle.
(I think)

Rhombus if the diagonals are going the same way. Trapezium if going opposite ways. I think.

'A special kind of rectangle'? WTF?

nicnack2 is that a rhombus?

Oi! I just said that!

your confusing me now LOL no seriously you are .
rectangle =?
oblong =?
square =?
triangle=?
hexagon=?
pentagon=?
and a six sided shape cant remember name =?

A rhombus has 4 sides of equal length, 2 pairs of parallel sides and opposite angles are equal - a square pushed over a bit. A trapezium has one set of parallel sides.

rectangle si any shape with 4 straight sides and 4 right angles. Both squares and oblongs are rectangles. Squares have all 4 sides of equal lenght. Oblongs have 2 long sides and 2 short sides.

yip a rhombus. Just looked at google and it says that a square is a plane rectangle with 4 equal sides and angles. rectangle is a quadilateral with 4 right angle.

An oblong is the same as a rectangle - rectangle is the word they use at school. Triangles can be equilateral - 3 sides the sme length and 3 angles of 60 degrees each, right-angled, isosceles - 2 sides same length and 2 angles the same or scalene - all sides difft lengths and all angles difft. We never did scalene triangles at school though - they must be new!

we did scalene - I'm 33!

Scroll down on my link - quite a useful site. I'm dreading the maths homework when mine are juniors and I'm an ex teacher!!

Good link, tallmummy. Never knew there were so many shapes.

We did scalene too and I'm 46 :)

As far as I'm concerned a square is a square and a rectangle/oblong is a rectangle/oblong. Both are quadrilaterals (4sides).

thank you tall mummy

An oblong does not have to be a rectangle. It is a shape that has been elongated, so a circle can be stretched and become an oblong.

A rectangle on the other hand has to be an oblong by definition.

Just to confuse things a bit

Interesting.

I thought a stretched circle was an oval.
Always thought an oblong had straight sides.

Well you live and learn.

OOh, the rectangle/oblong thing .

Rectangles are always oblongs, but oblongs do not have to be rectangles.

Oblongs, rectangles and squares\link{http://en.wikipedia.org/wiki/Rectangle\wikipedia definition}

Looks like a square is a "special rectangle" according to wikipedia.

S'what I said .

An egg is an oval (or ovoid I believe to be precise)
but it isn't strictly speaking a stretched circle - it pinches in to a point.
