LCHL Revision: Junior Certificate transformation geometry

These lessons will involve the students in investigating and understanding:

• Translations: an intuitive approach using drawings

Mathwords: Shift

• Axial symmetry: an intuitive approach using drawings

• Axis of symmetry

Mathwords: Axis of Symmetry

• Central symmetry- an intuitive approach using drawings

• Centre of symmetry

Axial symmetry,central symmetry,translations and their composite mappings are isometries (conserving measure of length, angle and area). - Fundamental Drawing Constructions
