Try it yourself first — open a section below only if you get stuck.
How to solve it
Use the scale that starts at zero on one arm of the angle, and check the reading against whether the angle looks acute or obtuse.
Worked example
An angle that clearly looks acute must read under 90, so 60 rather than 120.
Common mistake
Reading the wrong scale. The two rows of numbers always add to 180 at any position.
