No, parallelograms and rectangles cannot have reflex angles. This is because 1. The sum of their interior angles must be 360 degrees. 2. Opposite angles must be equal. 3. If it were the case that a reflex angle existed, two angles would have to be greater than 180 by 2. 4. But by 1, the two angles would now sum over 360, and that cannot occur for a four-sided polygon.
rectangle or square
the two acute angles have a sum of 90. If the ratio is 4:1, then there are five units to split. Divide the 90 degrees by 5.90/5 = 1818 * 4 = 72So the larger angle has a measure of 72 degrees and the smaller angle is 18 degrees.
A rhombus has 4 equal sides. Its angles can be right angles, but don't have to be. A square is a type of rhombus.
The shape is all of the following: -- quadrilateral -- parallelogram -- rectangle -- rhombus -- square
hexagon
A four edged star.
Any shape with 4 acute angles must have more than 4 sides. Any shape with more than 4 sides can have 4 acute angles (but doesn't have to).
An irregular dodecagon.

They are: acute, right angled, obtuse, reflex, straight, and i think thats about it

A rhombus.
It is a rhombus or a parallelogram
