<｜begin▁of▁sentence｜>### Instruction:
Given the center of a downward-facing triangle at coordinates (100, 200) and a source point at (50, 150), can you use the `intersection_point` method from `DownTriangleDrawer` in igraph to find where a line drawn from the source point to the center of the triangle intersects the triangle's boundary?
### Response:
from igraph.drawing.shapes import DownTriangleDrawer

# Define the center of the down triangle
center_x, center_y = (100, 200)

# Source point from which a line will be drawn towards the center of the triangle
source_x, source_y = (50, 150)

# Instantiate the DownTriangleDrawer drawer
drawer = DownTriangleDrawer()

# Determine the intersection point
intersection = drawer.intersection_point(center_x, center_y, source_x, source_y)

# Print the intersection point
print(f'Intersection Point: {intersection}')
