How many acute angles can a scalene triangle have?
1 Answer
A scalene triangle can have either
Explanation:
A scalene triangle is any triangle with no repeated angle measures.
There are three general ones:

An acute scalene triangle, where all
#3# of the angles are less than#90˚# . An example would be a triangle with degree measures#30˚# ,#70˚# , and#80˚# . All three of its angles have different measures and are all acute. (3 acute angles) 
A right scalene triangle. Any right triangle will have one degree whose measure is
#90˚# , and the other two angles must be acute. An example would be the very common#30˚60˚90˚# triangle, which, again, has two acute angles. (2 acute angles) 
An obtuse scalene triangle. This is very similar to the right scalene triangle, except it has one angle whose measure is greater than
#90˚# , and two acute angles. (2 acute angles)
