  1. Calculating the area of a leaning triangle

  2. Calculating Area

  3. Calculating Area Draw a rectangle (or square) around the triangle Area of triangle = ½ square The area of this rectangle = 1 square The triangle is ½ of the rectangle so its area = ½ square

  4. Calculating Area What about this triangle?

  5. Calculating Area Draw a rectangle around the triangle The area of this rectangle = 2 squares

  6. Calculating Area The area of the triangle can be calculated by taking away the area of the 2 white triangles

  7. Calculating Area The area of the first white triangle = ½ square

  8. Calculating Area The area of the second white triangle is ½ of the surrounding rectangle

  9. Calculating Area The area of the surrounding rectangle = 2 squares So the area of the second white triangle = 1 square

  10. Calculating Area Area of triangle = ½ square So the area of the triangle = 2 - ½ - 1 = ½ square
