1. The problem asks to identify the types of lines represented on a door made of seven rectangular pieces of wood joined together with some wood on top forming a zig zag pattern. 2. Rectangular pieces typically have straight edges that are parallel and perpendicular to each other. 3. A zig zag pattern consists of straight lines connected at angles, which are oblique lines (lines that are neither parallel nor perpendicular). 4. Therefore, the door shows both parallel lines (from the rectangular pieces) and oblique lines (from the zig zag pattern). 5. Among the options, the correct description is "Wavy and oblique lines" (option b) is incorrect because the lines are not wavy. 6. The correct answer is option d: "Curved and oblique lines" is incorrect because the lines are not curved. 7. Option e: "Perpendicular and parallel lines" is partially correct for the rectangular pieces but does not account for the zig zag pattern. 8. Since the zig zag pattern consists of oblique lines and the rectangular pieces have parallel lines, the best match is option b: "Wavy and oblique lines" is incorrect because the lines are not wavy. 9. The correct answer is option d: "Curved and oblique lines" is incorrect because the lines are not curved. 10. The best fitting answer is option e: "Perpendicular and parallel lines" because the rectangular pieces have perpendicular and parallel lines, and the zig zag pattern can be seen as a combination of these. Final answer: e. Perpendicular and parallel lines.
