  4. Fort Use the diagram of the fort below.

    A bird’s-eye view of a building shows the front L-shaped side, with the right and top sides of two sections of the building also visible.

    1. Make an isometric drawing of the fort.
    2. Make an orthographic drawing of the fort.
  5. Aerial Photography Another perspective in aerial photography is the “bird's-eye view,” which shows an object from directly overhead. What type of drawing that you have studied in this lesson is a bird's-eye view?

  6. Writing Photographs of buildings are typically not taken from a bird's-eye view. Describe a situation in which you would want a photo showing a bird's-eye view.

Visualization Think about how each net can be folded to form a cube. What is the color of the face that will be opposite the red face?

  1. A net has a red square in the center with green square left, yellow square below, purple square right, and orange square above, with a blue square on top of the orange.
  2. A net has a stack of four squares: purple, blue, orange, and yellow, from top to bottom. A red square is left of the orange and a green square right of the yellow.
  3. A net has a row of three squares: blue, green, and yellow, from left to right. An orange square is below the green. A red square is above the yellow with a purple to its right.
  4. A net has a red square with orange below and yellow to the right. A green square is left of the orange. A blue square is above the yellow with a purple to its right.
  5. Multiple Representations There are 11 different nets for a cube. Four of them are shown above.
    1. Draw the other seven nets.
    2. Writing Suppose you want to make 100 cubes for an art project. Which of the 11 nets would you use? Explain why.
