Triangle Classification - Sides (Level 1)

This math topic focuses on the classification of triangles based on their sides. It involves determining whether a triangle is equilateral (all sides equal), isosceles (two sides equal), or scalene (all sides different) through a series of problems. This topic is an introductory level practice in the broader subject area of geometry, specifically triangle classification. Each question provides a visual depiction of a triangle, and the student is asked to identify the type of triangle based on its side lengths.
