I'm very confused my professor is very confusing, and I need to do this for a project where when collision is detected the score goes up.

Your radius is twenty. Inside the loop, just test whether Euclidean distance between sqrg and blx is within 20.

Below is a stripped down example based on your code. It measures the distance between the centers of the two moving objects to determine if a collision has occurred. If you manage to get the ball to hit the square, the ball should bounce straight up:

from random import randint

from time import sleep

from graphics import *



def distance(p1, p2):

    return ((p2.x - p1.x) ** 2 + (p2.y - p1.y) ** 2) ** 0.5



wn = GraphWin("AK", 700, 700)



sqrg = Rectangle(Point(325, 625), Point(375, 675))

sqrg.setFill("red")

sqrg.draw(wn)



numx = randint(10, 700)



blx = Circle(Point(numx, 80), 20)

blx.setFill("blue")

blx.draw(wn)



xval, yval = 10, 0



bheading = 1



wn.getMouse()



for i in range(150):

    sqrg.move(xval, yval)



    if distance(blx.getCenter(), sqrg.getCenter()) < 25:

        bheading *= -1



    symbl = wn.checkKey()



    if symbl == "Right":

        xval = 10

    elif symbl == "Left":

        xval = -10



    sleep(0.1)



    blx.move(0, bheading * 20)

Cleary not a viable game as-is, but a demonstration of collision detection.
