What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
A trapezium, a kite, a number of miscellaneous quadrilaterals.
No plane geometric figure can have one acute and three right angle only, at least two other angles must be included

A right angle triangle has one 90 degree angle and two acute angles
No it is impossible for a right triangle to have an obtuse angle therefore it will have one right angle and two acute angles.
an angle with a acute and right angle

you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles

yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
No, a right angle is 90 degrees and an acute angle is one with less than 90 degrees.
A right-triangle has a right angle (90o) and two acute angles.
