No shape does. If a shape has four angles, the sum of the four angles is 360°. If two are right angles, their sum is 2 x 90° = 180°, leaving 360° - 180° = 180° for the two remaining angles. An acute angle is less than 90°, so the sum of two acute angles is less than 90° + 90° = 180°, but in this shape their sum must be equal to 180°; thus no shape can exist. If one angle is acute and the other is obtuse, then their sum can be 180° and the shape is a trapezium.
It can take the shape of 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees
A rhombus.
There is no polygonal shape which has exactly those angles. It is possible for a concave polygon with 6 or more vertices to have the given angles.
It can take the shape of 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees
