IB MYP 2 – Project Task: Parallel Lines in Real Life
IB MYP 2 Mathematics
Project Task – Parallel Lines in Real Life
Criteria Assessed: B (Investigating Patterns), C (Communicating), D (Applying Mathematics in Real-Life Contexts)
Project Overview
In this project, you will explore how parallel lines appear in real-life situations.
You will investigate angle relationships formed by transversals, analyze patterns,
and communicate your mathematical reasoning clearly.
Task Instructions
-
Real-Life Evidence:
- Take or collect at least 5 original photographs showing parallel lines in real life (e.g., railway tracks, road markings, building structures, window grills, notebook lines).
- Clearly label the parallel lines in each image.
-
Mathematical Investigation (Criterion B):
- Draw a transversal intersecting the parallel lines in at least 3 images.
- Identify and label corresponding, alternate interior, alternate exterior, and co-interior angles.
- Explain angle relationships using correct mathematical reasoning.
-
Communication (Criterion C):
- Present your findings in a poster, slideshow, or digital report.
- Use correct mathematical vocabulary and notation.
- Include diagrams and clear step-by-step explanations.
-
Real-Life Application (Criterion D):
- Explain why understanding parallel lines is important in architecture, engineering, or design.
- Describe one real-life problem where angle relationships help solve a practical issue.
