Keep in mind, however, that the above rule (namely, that the angles of a triangle add up to 180 degrees) is not false. In fact, it is true — however, it is only true in Euclidean geometry.

You could also make an argument using the angle-side-angle triangle congruence theorem. Click for Answer 2: One of the great elementary results in triangle geometry is the triangle midsegment theorem: ...

to develop students' language related to attributes of triangles (e.g., from 'it looks like a triangle' to 'it has three straight sides') Overarching Aims: 1. To expand students mathematical ...
