Why can't a quadrilateral have four obtuse angles
🔄 Click to see definition
Definition1/18
The sum of the 4 internal angles of a quadrilateral must sum to
360° (go look up the proof of this elsewhere).
For the sake of argument, let's call the 4 internal angles of a
quadrilateral A, B, C, and D.
If they were all obtuse, then (by definition):
180° > A > 90°
180° > B > 90°
180° > C > 90°
180° > D > 90°
If you add them all up, you find that for the sum of the angles
A+B+C+D
720° > A + B + C + D > 360°
but, A+B+C+D = 360°,
Since the assumption produces a result that contradicts this,
the assumption cannot be true.
