Introduction to Geometry

Unit code: MATH20222
Credit Rating: 10
Unit level: Level 2
Teaching period(s): Semester 2
Offered by School of Mathematics
Available as a free choice unit?: N




To give an introduction to the basic ideas of geometry and topology.


This course unit introduces the basic ideas of Euclidean and affine geometry, quadric curves and surfaces in Euclidean space, and differential forms, and the first ideas of projective geometry. These notions permeate all modern mathematics and its applications.


Learning outcomes

On successful completion of this module students will have acquired an active knowledge and understanding of the basic concepts of the geometry of curves and surfaces in the three-dimensional Euclidean space, and will be acquainted with the ways of generalising these concepts to higher dimensions.

Feedback methods

Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding.  Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback.  Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.
