Question

4. Understand Draw two lines of reflection through point A so that the composition of the reflections across the lines maps onto the image shown.

Answer 1

When a group of point is reflected across a line the distance of the points to the line must be equal, therefore the figure is inverted. With this in mind we can trace the intermediate step that is missing and finally draw the two lines.

Notice that the triangle get's inverted on each reflection around the lines.
