right angles and obtuse angles
Step-by-step explanation:
We assume that anything that <em>looks like</em> a right angle <em>is</em> a right angle.
The angles at the left end of each horizontal line are right angles.
The angles at the right end of each horizontal line are obtuse angles.
The angle where the diagonal lines meet is a right angle.
The shape contains right angles and obtuse angles.
