Affine and Euclidean Geometry: Course Outline (MAT203)
Vector spaces and affine geometry:
Collinearity of three points, ratio AB/BC. Linear combinations and linear dependent set versus affine combinations and affine dependent sets. Classical theorems in affine geometry: Thales, Menelaus, Ceva, Desargues.
Affine subspaces, affine maps. Dimension of a linear subspace and of an affine subspace.
Scalar product, Cauchy-Schwartz inequality: norm of a vector, distance between two points, angles between two non-zero vectors. Pythagoras theorem, parallelogram law, cosine and sine rules. Elementary geometric loci.
Isometries of plane (four types), Isometries of space (six types).Orthogonal bases.
Euler theorem on finite planar graphs. Classification of regular polyhedra in space.
Isometries of regular polygons and regular polyhedra.
