Polygons and Coordinate Grids and Triangles

In math we learned about coordinate grids. You must start at the X axes, then the Y axes. On the computer, we would enter the coordinates correctly to create a polygon. Example:     (-50, 40) to (-30, 20)

We would use setxy to create the lines that connect to the vertices. And jumpto to tell it where to start. Polygons can not have 2 or less sids. It must have only straight sides. None curved. It can't have any openings.

There are many types of triangles. There is scalene, right, equilateral, isosceles, obtuse, and acute. A right triangle, has one right angle. An obtuse has one angle larger than 90 degrees. A scalene has no equal sides. An isosceles has two equal sides. equilateral has three equal sides. An acute has one angle smaller than 90 degrees. Did I cover them all? Bye!
