Indicates which angle is greater
In drawing A, we can see that the angle is an obtuse angle, meaning it is larger than 90 degrees:
While in drawing B, the angle is a right angle, meaning it equals 90 degrees:
Therefore, the larger angle appears in drawing A.
Indicates which angle is greater
Compare it to a square corner (like the corner of a book). If the angle opens wider than a square corner, it's obtuse. If it matches exactly, it's a right angle.
Acute angles are smaller than 90° (sharper than a square corner), while obtuse angles are larger than 90° (wider than a square corner). Right angles are exactly 90°.
Yes! Even though both are obtuse (> 90°), one can still be larger than the other. For example, 120° > 100°, even though both are obtuse angles.
The actual angle measurement is what matters, not how it's drawn. However, clear drawings help you identify the angle type correctly. Always look at the opening between the two rays.
Use reference angles! Compare both angles to a right angle (90°) first. Then use other references like or to help estimate and compare.
