TWO DIMENSIONAL SHAPES THAT HAVE 8 ANGLES FULL

On the left is a special type a rectangle not only are all the corners square not all do they have these right angles but all the sides are Rectangles now you might recognize this purple one Rectangle as well so these are both these are both The corners are right angles so this actually is a Squares I could put all squares in the corner or I could see that they are all right all One also is not a rectangle notice the corners are not the corners are not right angles so this is a direct rectangle this is aĭirect rectangle and what about this well I can do that I can put little Rectangle all four corners need to be square this It is this or neither is this so this is not a This so this is not a square corner neither Sides of a square or would look like or it would look like This corner right over if I tried to pull all square here it would either look like this orĭoesn't it doesn't the two sides aren't two Just to be clear this down here is not a rectangle notice Rectangle you are dealing with the rectangle and so SO if all four corners are square or they're all come in at a right angle like this then you're dealing with a Sometimes you could call it a right angle so and notice I could put little small squares Shape right over here what you might see is the corners theĬorners all come in, sometimes is called square It's a quadrilateral Let's think about each of these so this One two three four sides as long as as four sides Looks like this, could even have a quadrilateral that look like this. These are all different special cases of quadrilaterals and actually you could even have a quadrilateral that Sides is quadrilateral Quad dri quadrilateral quadrilateral and when you see this quadĪt the beginning of the word it's a pretty good sign that you'reĭealing with the number four four sides, four sides that's what quadrilateral means but Well if you count them you see that this one up here in purple has one two three four sides this one has one two three four sides, this has one two three four sides, this has one two three four sides. Over here these shapes are interesting how many This is a triangle has three sides note about these shapes Hear that's a good sign that you're dealing with the number Triangle Tri angle whenever you see this Tri over One two three if you have three sides we call that a Now whatĪbout the shape over here that has three sides one two three you could also say it has three corners This one right over here is not a circle, this one is.

Shorter than this distance right over here so In that direction is going to be much shorter or just Oval is not a circle because if you have its center see right over there this distance going Like this to be what you might call this an oval. Length so that's the same length as is this as this is on his way to theĬenter the circle as that now if that the circle what would something Of the circle to the other side circle through the center that's always going to be the same Think about it is if we take the center the circle and if we go from one side Now what makes it a circle when you getįurther in math we come up with fancier ways to define a circle but one with

Recognize it is the shape of the moon in the sky or atleast on a full moon and we call it a circle. I have a bunch of shapes here, let's thinkĪbout what they are so this first shape here, you probably
