Step-by-step drawing to show one possible solution to the puzzle in a series of nine images.

The first image shows the complete shape outlined in blue with a circle in the bottom left hand corner of the square to mark the starting point.

The second image shows an arrow pointing from the circle to the bottom right hand corner of the square and the line connecting these two corners has now turned orange.

The third image has replicated the second image but also has an arrow pointing from the bottom right hand corner of the square to the top left hand corner of the square. This line has now also turned orange.

The fourth image has replicated the third image but also has an arrow pointing from the top left hand corner of the square to the top right hand corner of the square. This line has now also turned orange.

The fifth image has replicated the fourth image but also has an arrow pointing from the top right hand corner of the square to the top of the triangle. This line has now also turned orange.

The sixth image has replicated the fifth image but also has an arrow pointing from the top of the triangle to the bottom left corner of the triangle/top left corner of the square. This line has now also turned orange.

The seventh image has replicated the sixth image but also has an arrow pointing from the bottom left corner of the triangle/top left corner of the square to the bottom left corner of the square (starting point). This line has now also turned orange.

The eighth image has replicated the seventh image but also has an arrow pointing from the bottom left corner of the square (starting point) to top right corner of the square. This line has now also turned orange.

The ninth and final image has replicated the eighth image but also has an arrow pointing from the top right corner of the square to the bottom right corner of the square. This line has now also turned orange meaning the whole line drawing is orange.
