INTRODUCTION TO
PLANE GEOMETRY
ASSUMED KEDE
Students i have had etensive informa eperience ith geometry in earier years, and
this i provide a good intuitive basis for the more systematic approach to geometry
appropriate in ears –10 The particuar topics from ears F– reevant to this modue are
• The use of compasses and ruers and the carefu draing of geometrica figures
• Types of anges, incuding at east right anges, acute anges, obtuse anges and
refle anges
• Trianges, incuding an informa introduction to isoscees and euiatera trianges
• uadriateras, incuding an informa introduction to suares, rectanges,
paraeograms, trapeia and rhombuses
• nforma eperience ith transations, reflections, rotations and enargements,
and ith symmetry in the contet of activities such as foding an isoscees triange,
rectange or rhombus
MTIATI
eometry is used to mode the ord around us vie of the roofs
of houses reveas trianges, trapeia and rectanges, hie tiing
patterns in pave ments and bathrooms use heagons, pentagons,
trianges and suares
uiders, tiers, architects, graphic designers and eb designers
routiney use geometric ideas in their or Cassifying such
geometric ob ects and studying their properties are very important
eometry aso
has many appications in art
¡ust as arithmetic has numbers as its basic ob ects of study, so points, ines and circes are
the basic buiding bocs of pane geometry
