  2. What you will learn about triangles • What a triangle is • The four different kinds of triangles and the differences between them

  3. Properties of Triangles • All triangles have 3 sides • All triangles have 3 angles • The three angles will always add up to 180 

  4. There are 4 kinds triangles • Right • Equilateral • Isosceles • Scalene

  5. The Right Triangle • The right triangle has a special corner that is 90 degrees. This called a “right angle” • The other 2 corners will add up to 90 totaling 180 for the whole triangle Right Angle

  6. The Right Triangle • Right triangles also have a special side called the hypotenuse • The hypotenuse is the side opposite the right angle Hypotenuse Right Angle

  7. Equilateral Triangle • Equilateral Triangles have 3 sides • Each side is the same length. • Each corner has the same degree which is 60 .Three corners that are 60 equal 180

  8. Isosceles Triangle • Isosceles Triangle has 3 sides. 2 of the sides are of equal length. • 2 of the corners are the samedegree • The 3 corners will still add up to 180

  9. Scalene Triangle • Scalene Triangle has 3 sides. • None of the sides are equal. None of the corners are equal in degrees. • If you add up the corners, they will still equal 180

  10. In Review Can you match the name of the triangle with its picture? Right Isosceles Scalene Equilateral

  11. Good job! The End!
