A heptagon.
A shape with four unequal sides is called an irregular quadrilateral.
They are perpendicular lines that meet at right angles which is 90 degrees.
This is a parallelogram called a rectangle. A square has four right angles and four sides that are equal in length.
four, one for each corner. If a corner is not a right angle, the shape is then called a rhombus.
A shape with 7 sides and 7 angles is called a heptagon. A heptagon is a polygon with seven straight sides and seven interior angles. Each interior angle of a regular heptagon measures 128.57 degrees.
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 seven sided shape (with seven angles) is called a heptagon.
A seven sided shape is a heptagon.
A shape with parallel sides but no right angles is called a parallelogram
An irregular heptagon.
An irregular heptagon.
Because of its right angles.
a Pentagon is five sided and CAN have 3 right angles.
A shape with 8 sides is called an octagon. If it has 4 right angles, it can be classified as a right octagon, which is a specific type of octagon where some angles are right angles. However, a regular octagon does not have right angles; thus, a shape with 8 sides and exactly 4 right angles may be an irregular octagon. An example could be a shape resembling a rectangle extended into an octagonal form.
Such a shape is called a rhombus.
