Euclid's great synthesis of Greek geometry, The Elements, was for centuries regarded as a model of abstract axiomatic reasoning, but in the 19th century a close examination of the foundations of mathematics led to the realization that Euclid's axiomatic structure is actually quite deficient in many respects. With knowledge of the sides and angles you can start subgrouping the group of triangles into isosceles, equilateral and right-angled ones. If X, Y, Z are three sides of the triangle. In equilateral triangles all the sides are equal. Properties of triangle.
