TRIANGLESCLASSIFICATIONS, ANGLES AND MORE!!Mr. Deepak Kumar
Different Types of TrianglesThere 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 SidesEQUILATERAL – 3 congruent sidesISOSCELES – at least two sides 	congruentSCALENE – no sides congruentEQUILATERALISOSCELESSCALENE
Classifying Triangles by Their AnglesEQUIANGULAR – all angles are congruentACUTE – all angles are acuteRIGHT – one right angleOBTUSE – one obtuse angleEQUIANGULARACUTERIGHTOBTUSE
Can You Classify the Different Triangles in the Picture Below?Classify the following triangles: AED, ABC, ACD, ACE
The Classifications…Triangle AED = Equilateral, EquiangularTriangle ABC = Equilateral, EquiangularTriangle ACD = Isoceles, ObtuseTriangle ACE = Scalene, RightSo how did you do?
