in class we are learning about polygons. polygons are shapes that only have staight lines and has to have 3 of more sides. a hexagon is a polygon. we are learning how to put polygons on grids. we go on Geo-Leo. this is a computer promgram that teachs us about polygons and coordinate grids. different angles that make different Triangles or squares. now i will talk about The different kinds of triangles.
There are many different kinds on triangles that are different because of there sides and angles. if onw of the angles is 90 degrees than the traingle is called a right triangle. if all the sides are the same and all the angles are the same size than the triangle is called a Equilateral Triangle. if two of the sides are the same than it is called a isosceles triagngle. and the last kind is a scalene triangle which is a triangle that none of the sides are the same and none of the angles are the same.
and last i will tell you about coordinate grids. coordinate grids are grids that have four different spaces. to tell the differents of the spaces is two lines one line is called the y. that is the line that runs up and down. the other line is called the x. this is the line that runs side to side. to know where things are there are different #'s run down the sides of the x and y lines. to find a place on the grid you have to read a set of #'s that look like this. [40,60]. the #'s are all different.
