Geometrical Terms
Akopọ
Geometry has its own precise vocabulary, and getting that vocabulary right is the difference between a confident answer and a confused one. A vertex is not just a corner, a chord is not the same as a diameter, and congruent means something quite different from similar. Once the words are exact, the shapes start to make sense.
In this lesson you will build the language of geometry from the ground up: points and lines, the four kinds of angle, the families of triangles and quadrilaterals, polygons and their nets, and every part of a circle from its centre to its segment. No drawing is needed here, only clear definitions you can rely on for the rest of the course.
