A shape with 3 right angles and 2 obtuse angles is a pentagon. A pentagon is a five-sided polygon, and when three of its angles are right angles (90 degrees each) and two are obtuse angles (greater than 90 degrees each), it meets the criteria specified. This specific type of pentagon is known as a concave pentagon, as it has at least one interior angle greater than 180 degrees.
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
