Isosceles triangle properties

समद्विबाहु त्रिभुज के गुणधर्म

In this Class 9 Mathematics topic from the chapter Triangles, students study the defining properties of an isosceles triangle: two equal sides and the equal angles opposite them. They learn how to identify the base and base angles, use the theorem that equal sides subtend equal angles, and understand its converse. The topic also connects these ideas with proofs, angle calculations, constructions, and solving geometric problems involving symmetry and congruent triangles.
