Draw one row of five equilateral triangles, like shark teeth painted on the road. Use black outlines on a white canvas. Leave the triangles unfilled.

Each triangle has sides that are 50 steps long. All triangles point down and touch side by side. Start each triangle facing right. The first triangle starts at (-125, 55). Move 50 steps to the right for each next triangle. Their starting x-coordinates are -125, -75, -25, 25, and 75.

Write a function named draw_triangle that draws one triangle. The function does not need a parameter. Repeat these steps three times inside the function: move forward 50 steps, then turn right by 120 degrees.

Call your function at all five starting points. Use penup() and goto() to move between triangles without drawing connecting lines.
