Matplotlib python

I have the following problem:

I have a Python script that has a class called "Triangle" which has a method called "plot ()", it returns the graph of a triangle. In this same script I have another class called "Circle" that has a method called "plot ()", this returns the graph of the circle. With the above I want to create a method in the class "Triangle" that I graph the triangle and circle in a single graph from their respective methods --- observe the method (plotintrianglecircle) . How can I achieve the above?

I am using matplotlib. I've tried for a long time but I still can not.

I have done the following in code:

This is the "Circle" class:

class Circle():

    def __init__(self, center, radius):
        self.center = center
        self.radius = radius

    def plot(self):

        from matplotlib import pyplot as plt
        import numpy as np

        alpha = np.linspace(0, 2 * np.pi, 1000)
        self.x = self.center[0] + self.radius * np.cos(alpha)
        self.y = self.center[1] + self.radius * np.sin(alpha)
        fig = plt.figure()
        ax = fig.add_subplot(111)
        # plot circle
        ax.plot(self.x, self.y, 'r-', label='Circle')
        ax.axis('equal')
        ax.grid(ls='--', lw=0.6)
        ax.legend()
        return ax

For the Triangle class I have the following code:

 class Triangle():

    def __init__(self, vertices):

        import numpy as np

        # (3, 2) Array of triangle vertices
        self.v = np.array(vertices)

    def plot(self):

        import numpy as np
        from matplotlib import pyplot as plt

        fig = plt.figure()
        ax = fig.add_subplot(111)
        # plot triangle
        ax.plot(np.hstack((self.v[:, 0], self.v[0, 0])),
                np.hstack((self.v[:, 1], self.v[0, 1])),
                'k-', label='Triangle')
        ax.axis('equal')
        ax.grid(ls='--', lw=0.6)
        ax.legend()
       return ax

    def intrianglecircle(self, radius=None):

        import numpy as np

        if radius is None:
            self.radius = 0.05 * self.inradius()
        else:
            self.radius = radius
        # random number [0, 1]
        r1, r2 = np.random.random(), np.random.random()
        # x-coordinate
        px = (1-np.sqrt(r1))*self.v[0][0]+(np.sqrt(r1)*(1-r2)) * \
            self.v[1][0]+(np.sqrt(r1)*r2)*self.v[2][0]
        # y-coordinate
        py = (1-np.sqrt(r1))*self.v[0][1]+(np.sqrt(r1)*(1-r2)) * \
              self.v[1][1]+(np.sqrt(r1)*r2)*self.v[2][1]
        # center circle
        self.center = np.array([px, py])
        return Circle(self.center, self.radius)

        def plotintrianglecircle(self):

            import numpy as np

            c = Circle(self.center, self.radius)
            fig2 = c.plot()
            fig2.plot(np.hstack((self.v[:, 0], self.v[0, 0])),
                       np.hstack((self.v[:, 1], self.v[0, 1])),
                       'k-', label='Triangle')
            fig2.legend()
            return

Observe the plotintrianglecircle method of the Triangle class. What I want to do is just reuse the plot method of the Triangle class . strong> to avoid writing the lines where fig2.plot (....) . How can I do it?

You can execute the code with these data so that you can see the result:

vertices = [[2, 1.5], [4.5, 4], [6, 2]]
t = Triangle(vertices)
t.intrianglecircle(1)
t.plotintrianglecircle()

I just want to reuse the plot method of the Triangle class as I mentioned earlier.
