CLASSIFICATIONS, ANGLES AND MORE!!
There are several different types of triangles.
You can classify a triangle by its sides and its angles.
There are THREE different classifications for triangles based on their sides.
There are FOUR different classifications for triangles based on their angles.
EQUILATERAL – 3 congruent sides
ISOSCELES – at least two sides
SCALENE – no sides congruent
EQUIANGULAR – all angles are congruent
ACUTE – all angles are acute
RIGHT – one right angle
OBTUSE – one obtuse angle
Classify the following triangles: AED, ABC, ACD, ACE
Triangle AED = Equilateral, Equiangular
Triangle ABC = Equilateral, Equiangular
Triangle ACD = Isoceles, Obtuse
Triangle ACE = Scalene, Right
So how did you do?
