Answer 16

when you classify triangles you can sort them by sides or by angles.
if all 3 sides are equal--> equilateral (latin for equal side)
2 sides equal --> isosceles
no side equal --> scalene

by angle:
all angles < 90 --> acute
1 angle = 90 --> right
1 angle > 90 ---> obtuse

you can have combinations if you use both angle and side: e.g. right isosceles

of course an equilateral triangle (3 = sides) also has 3 = angles. Because they angles must add up to 180, they are 60 each. All angles<90 means it is acute.
