Explanation:
Acute: angle from 1-89 degrees
Right angle: Only 90 degrees
Obtuse: is more than 90 but not more than 180 degrees
A triangle always has 3 sides but sometimes they have different measurements and lengths but they always add up to 180
Scalene: all the sides are different but they all add up 180 which meets the standards of a triangle
Isosceles :Have 2 opposite sides that look are identical but one of them is different
Equilateral means that all 3 sides are equal ( remember that from the name)
