An obtuse angle is something bigger than 90 degree's and if you know what a right angle is an obtuse angle is bigger than a right angle. HOPE IT HELPS!
What Does An Obtuse Angle Look Like?
If you look at a right angle,(90degrees)it will be bigger.An acute angle is smaller.I had a hard time with that too and asked the same answer!It's really hard so check with a grown-up and see if you aredoing it right.-Don't want to get a F on your geometry test!
Any angle greater than 90 degrees.
