No. For example a parallelogram does not have any right angles. The internal angles of all four sided shapes will always equal 360 degrees, but do not necessarily have to include right angles.
Square, Rhombus, Rectangle and four right angles put together.
No because a 4 sided rectangle also has four right angles
A four sided figure with four equal sides and no right angles is a diamond, or a rhombus. If it had four right angles, it would be a square.
No. Only squares and rectangles have 90 degree angles. There are other 4-sided shapes, such as a rhombus, a diamond, and a trapezoid that have 2 angles that are larger than 90 degrees and 2 angles that are smaller than 90 degrees.
A four-sided polygon with all sides congruent and with four right angles is a square.
No. A trapezoid is any four sided shape which has at least two parallel sides. If it is four sided, cannot have exactly four right angles.
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
A square or a rectangle
No because a rectangle also has 4 right angles.
