Episode 14 — Euclidean Geometry

Midpoint Theorem

Learners will be able to:

• Identify the midpoints of the sides of a triangle in a given diagram. • Explain why DE is parallel to BC and half the length of BC. • Determine the length of side BC using the midpoint theorem. • Calculate the length of AC by doubling the length of DF. • Apply the midpoint theorem to find the lengths of other sides of a triangle.
