Different Types of Triangles
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.
Classifying Triangles by Their Sides
EQUILATERAL – 3 congruent sides
ISOSCELES – at least two sides
congruent
EQUILATERAL
ISOSCELES
SCALENE – no sides congruent
SCALENE
Classifying Triangles by Their
Angles
EQUIANGULAR – all angles are congruent
ACUTE – all angles are acute
EQUIANGULAR
RIGHT – one right angle
ACUTE
RIGHT
OBTUSE – one obtuse angle
OBTUSE
Can You Classify the Different
Triangles in the Picture Below?
Classify the following triangles: AED, ABC, ACD, ACE
The Classifications…
Triangle AED = Equilateral, Equiangular
Triangle ABC = Equilateral, Equiangular
Triangle ACD = Isoceles, Obtuse
Triangle ACE = Scalene, Right
So how did you do?
