This first look at
triangles during the first two years of secondary education is mainly
focused on the following: constructing triangles using a ruler and
compass, characteristics of equal triangles, angles and area. Before
studying this unit students should be familiar with how to measure
angles and carry out operations with them.
Although
the study of special lines in a triangle usually takes place during
the third and fourth years of secondary education a general
introduction to this area in the second year is useful, and the Nippe
Descartes programme is an excellent way of doing this.
