Isosceles-Equilateral Triangle (TYT)
Learning Time: 3-10 hours
Content: Isosceles and equilateral triangles are a subject that examines special types of triangles. The TYT curriculum focuses on the definition of an isosceles triangle (congruence of two sides and angles), the properties of an equilateral triangle (congruence of three sides and angles), basic proofs, and practice problems. This topic forms the basis for understanding the symmetry of triangles. The updated 2025 TYT curriculum also includes measurement techniques and examples from daily life.
