Solution Steps

Step 1: Identify the Intersecting Planes
  • The roof and exterior walls of the house represent intersecting planes. We need to identify the lines formed by these intersections.
Step 2: List the Intersecting Lines
  • The lines formed by the intersecting planes are the edges of the house. These edges are:
    • AB, AD, AE, BC, CD, DA, CA, EF, EG, EH, and GH.
Step 3: Match the Correct Option
  • Compare the listed lines with the given options:
    • Option A: AC, AD, AE, BC, CD, DA, CA, EF, EG, EH
    • Option B: AB, AD, AE, BC, CD, DA, CA, EF, EG, EH
    • Option C: AB, AD, AE, BC, CD, DA, CA, EF, EG, EH
    • Option D: AB, AD, AE, BC, CD, DA, CA, EF, EG, EH

Final Answer

  • The correct option is Option D: AB, AD, AE, BC, CD, DA, CA, EF, EG, EH.
