Circle Theorems: 12 Theorems Based on Circles

The video tutorial covers theorems related to circles, focusing on equal chords, their converse, and angles subtended by arcs. The teacher explains how to prove these theorems using properties of triangles and congruency. The session includes a recap of previous theorems and introduces new ones, emphasizing the importance of understanding the relationships between angles, chords, and arcs in a circle.
