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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
