Euclidean General Triangle measured
Characteristics of All Triangles in Euclidean Geometry
What are some common characteristics of all triangles in Euclidean
Geometry?
What is the sum of the measures of the interior angles?
What is the relationship among the relative lengths of the sides and the
relative measures of the interior angles? E.g. what can you say about
the hypotenuse (longest side) and the largest angle?
