  • Area and perimeter
    • The formula for the area of a triangle is: area=1/2 (base x perpendicular height)
    • A compound shape is made up from other, simpler shapes
      • To find the area of a compound shape, divide it into basic shapes
      • To find the perimeter, start at one corner of the shape and travel around the outside, adding the lengths
