Triangle classification
1 like733 views
This document discusses two ways to classify triangles: by their side lengths or by their angles. For side classification, triangles are either scalene with no equal sides, or isosceles with at least two equal sides. For angle classification, triangles are either acute with all angles less than 90 degrees, right with one 90 degree angle, or obtuse with one angle over 90 degrees. Examples are given of classifying triangles into these different categories.
