An irregular heptagon.
A seven sided shape is a heptagon.
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.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A shape with parallel sides but no right angles is called a parallelogram
It is a heptagon that is a polygon having 7 sides with 7 interior angles.
A seven sided shape (with seven angles) is called a heptagon.
A heptagon.
A RECTANGLE has 4 sides and 4 right angles.
This shape has only one pair of opposite sides and no right angles: <
No sides perpendicular means no right angles. A rhombus is a quadrilateral with no right angles so no sides perpendicular.
A rectangle has two right angles and parcel sides
The following shape has three sides and the only angles are right angles. ----- | |___
