-----> Drag the three vertices A, B and C around -----> Press space to change the color inside the circle -----> See the type of triangle (Acute - Right - Obtuse) or (Isosceles - Equilateral, Scalene) -----> See the values of angles A, B and C and the values of the sides AB, AC and BC. -----> Use the arrows keys to move the vertix C.
I made this project to test a very simple block to fill a triangle with free vertices. I have difficulties to find the Equilateral triangle. If you have any idea tell me in comments. Thanks ffred for the idea (types of triangles) http://scratch.mit.edu/projects/3310982/
