  2. Scalene Triangle

  3. Scalene Triangle A scalene triangle is a triangle with no congruent sides.

  4. Scalene Triangle The sides of the scalene triangle were 10, 23, and 15.

  5. Scalene Triangle

  6. Scalene Triangle If a triangle has two sides the same is it a scalene triangle? If a triangle has all three sides the same is it a scalene triangle? If a triangle has sides measuring 3, 4, and 5, is it a scalene triangle?

  7. Equilateral Triangle

  8. Equilateral Triangle An equilateral triangle is a triangle with three congruent sides.

  9. Equilateral Triangle The equilateraltriangle had all sides measuring 30 centimeters.

  10. Equilateral Triangle

  11. Equilateral Triangle Can an equilateral triangle have only two sides equal? Is each angle in an equilateral triangle equal to 60 degrees? Do equilateral triangles add up to 360 degrees?

  12. Isosceles Triangle

  13. Isosceles Triangle • An isosceles triangle is a triangle with two congruent sides.

  14. Isosceles Triangle Theisosceles triangle looks a lot like a pyramid.

  15. Isosceles Triangle

  16. Isosceles Triangle Does an isosceles triangle have 180 degrees? Are all three sides of an isosceles triangle the same? Does an isosceles triangle have two congruent sides?

  17. Triangle Sum Theorem

  18. Triangle Sum Theorem The Triangle Sum Theorem states that the sum of the measures of the angles in a triangle is 180 degrees.

  19. Triangle Sum Theorem • The Triangle Sum Theorem says that: if a triangle has angles measuring 60 degrees, 80 degrees, and 40 degrees the sum will equal 180 degrees. 60º + 80º + 40º = 180 º.

  20. Triangle Sum Theorem

  21. Triangle Sum Theorem Do the angles of all triangles add up to 360 degrees based on the Triangle Sum Theorem? Do the sides of all triangles add up to 180 degrees based on the Triangle Sum Theorem? Do all angles in a triangle add up to 180 degrees?

  22. Triangle Inequality Theorem

  23. Triangle Inequality Theorem The Triangle Inequality Theorem says the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

  24. Triangle Inequality Theorem If a triangle has sides which measure 5 in. by 9 in. by 8 in. the following will be true based on the Triangle Inequality Theorem: 5 + 8 > 9 8 + 9 > 5 9 + 5 > 8

  25. Triangle Inequality Theorem

  26. Triangle Inequality Theorem Can a triangle have sides measuring 4 in. by 2 in. by 8 in. based on the Triangle Inequality Theorem? Can a triangle have sides measuring 4 in. by 5 in. by 3 in based on the Triangle Inequality Theorem?

  27. Opposite Side-Angle Theorem

  28. Opposite Side-Angle Theorem • The Opposite Side-AngleTheorem states that: If one side of a triangle is longer than another side, then the angle opposite the longer side is larger than the angle opposite the shorter side.

  29. Opposite Side-Angle Theorem

  30. Opposite Side - Angle Theorem

  31. Complementary vs Supplementary Angles
