Glossary
Midpoint — the exact middle point of a side.
Median — a line from a vertex to the midpoint of the opposite side.
Centroid (G) — where all 3 medians meet; the triangle's "centre of mass".
Perpendicular Bisector — a line through a side's midpoint, at 90° to that side.
Circumcentre (O) — where the perpendicular bisectors meet; equally distant from all 3 vertices.
Angle Bisector — a line splitting a vertex's angle exactly in half.
Incentre (I) — where the angle bisectors meet; equally distant from all 3 sides.
