Answer:
1. Acute 2. Obtuse 3. Right
Step-by-step explanation:
Obtuse Triangle Definition
An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It's impossible for a triangle to have more than one obtuse angle.
Acute Triangle Definition
An acute triangle is defined as a triangle in which all of the angles are less than 90°. In other words, all of the angles in an acute triangle are acute.
A Right Triangle has a right angle
