IB Math AI SL 3.5 - Equations of Perpendicular Bisectors

This IB Math AI SL 3.5 Equations of Perpendicular Bisectors slide deck builds student confidence in a key geometry concept by breaking the process into clear, structured steps aligned with the syllabus. Students learn how to find and interpret perpendicular bisectors using both coordinate pairs and given line equations, supported by annotated explanations and visual reasoning.

The lesson guides learners through finding midpoints, calculating gradients, determining perpendicular slopes, and forming equations using point–slope form. Carefully scaffolded examples and practice problems reinforce understanding, while real-world applications (such as Wi-Fi coverage boundaries and village planning scenarios) help students see how perpendicular bisectors model equal distances in practical contexts.

With its emphasis on visual learning, methodical problem-solving, and exam-style practice, this slide deck is ideal for classroom instruction or independent revision, equipping students with the skills needed to confidently tackle IB assessment questions in coordinate geometry.
