  1. Tricky Triangles Geometry in the Real World Sam Rose and Taylor Friday

  2. What are Triangles Triangles have: Triangles have three sides Three angles 180 degrees Triangles can be classified by two ways: By their sides By their angles

  3. Measuring 2D triangles There are two ways to measure triangles: Perimeter (add up all sides a b c) Area (1/2 Base x Height)

  4. Triangular Prisms Two ways to Measure Triangular Prisms: Volume (area of triangle x length) Surface Area (find area of all sides add together)

  5. Triangular pyramid Two ways to measure triangular pyramids: Volume (1/3BH) Surface Area (find area of all sides add together)

  6. Comprehension Questions What is a triangle? How many sides?

  7. Comprehension Questions How many ways are there to measure a 2D triangle? How many types of 3D triangles? How many ways are there to measure a 3D triangle?
