Use Python and Turtle and Random library to draw the 50 random isosceles triangles as shown in the following figure.
Hints:
- Make a function that draws isosceles triangle given the center of the base, length of the base, height, and the direction from the base to the top of the triangle.
- Use random library’s uniform function to generate positions, size, direction, and color.
