Types of Triangles

Angles

The angles in a triangle add up to 1800

60o + 60o + 60o = 1800

Triangles can be classified in two ways

You can name triangles by their angles

You can name triangles by their sides

Page 4: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Acute Triangle

All angles measure less than 90º

Page 5: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Right Triangle

One angle measures exactly 90º

Page 6: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Obtuse Triangle

One angle measures more than 90º

Page 7: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Scalene Triangle

All sides are different lengths

Page 8: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Isosceles Triangle

Two sides have the same length

Page 9: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

Equilateral Triangle

All sides have the same length

Page 10: Types of Triangles. Angles The angles in a triangle add up to 180 0 60 o + 60 o + 60 o = 180 0

PracticeCan you name each triangle by its

sides and its angles?
