the coordinate plane given coordinates for the vertices".
It's a game with 4 levels.
1.- You draw triangles touching on the screen. App tell you if they are scalenes, isosceles, acute, obtuse or right.
2.- App give you pairs (x,y) of vertices to draw triangles.
3.- You must draw the required triangle (scalenes, isosceles, acute, obtuse or right).
4.- App give you pairs (x,y) to draw quadrilaterals, pentagons and hexagons.
You increase your score with right answers and doing the job quickly. At the end you get your total score.
