An acute triangle has 3 _____ angles, 5th grade missed a whole week of school. Really confused, last week we were working on dividing fractions now we're working on geometry
An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.
