polygons

• Irregular polygon


  • Located on top of a graph
  • Can be broken down into two triangles and a square
• Finding the total area of the irregular polygon

  1. Draw lines to break the figure into easily recognizable shapes (two triangles and a square)

  2. Determine the base and height of each triangle

  3. Calculate the area of the square

  4. Consider the two triangles as a single rectangle and calculate its area

  5. Add the area of the square and the two triangles
• Base and height of a triangle


  The two lines of the triangle that form the right angle
• The base of the first triangle is 4 units and the height is 7 units
• The base of the second triangle is also 4 units and the height is also 7 units
• The square has a side length of 7 units
• The two triangles are congruent
• The two congruent triangles can be considered as a single rectangle with a base of 4 units and a height of 7 units
