  build() {
    Column({ space: 10 }) {
      // Draw a triangle in a 100 x 100 rectangle. The start point is (0, 0), the end point is (100, 0), and the passing point is (50, 100).
      Polygon({ width: 100, height: 100 })

        .fill(Color.Green)
      // Draw a quadrilateral in a 100 x 100 rectangle. The start point is (0, 0), the end point is (100, 0), and the passing points are (0, 100) and (100, 100).

      // Draw a pentagon in a 100 x 100 rectangle. The start point is (50, 0), the end point is (100, 50), and the passing points are (0, 50), (20, 100), and (80, 100).
