What types of angle are 78 degrees and 144 degrees?
78- acute 144- obtuse This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD =90 is right angel And anything above 90 and below 360 is obtuse because it's fat xD
144 is obtuse because it is more than 90. 78 is acute because it is less than 90
