A seven sided shape is a heptagon.
It is a heptagon that is a polygon having 7 sides with 7 interior angles.
A shape with seven sides and seven angles is called a heptagon. If it has three right angles, the other four angles must sum to a total of 360 degrees (since the total interior angle sum of a heptagon is 900 degrees). This means that the remaining angles can vary, but they must be arranged in such a way to maintain the heptagon's properties while accommodating the three right angles.
