err... no i dont think so, well the whole triangly makes up 180 degrees.

right triangle. pretty easy! lol. if it makes a right angle it should be a right triangle. if it is acute. it is an acute triangle, and the same with obtuse. its all simple to remember
Right = 90 degrees, acute = less than 90 degrees, obtuse = over 90, but less than 180 degrees. (between 180 and 360 is called "reflex".) A right triangle contains one right angle; an obtuse triangle contains one obtuse angle; and an acute triangle contains only acute angles.
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)
Right triangles have two acute angles, but that doesn't make them right. Having a right angle makes them right.
