Class 10th // Math // Circle // part 7 // by Shashank Yadav sir Definitions: Radius, diameter, chord, arc, sector, and segment. The center of the circle. Properties: The relationship between radius and diameter. Properties of tangents and secants. Angles subtended by arcs and chords. Theorems: The tangent-secant theorem. The angle in a semicircle is a right angle. Angles subtended by the same arc are equal. Equations of Circles: Standard form: ( 𝑥 − ℎ ) 2 + ( 𝑦 − 𝑘 ) 2 = 𝑟 2 (x−h) 2 +(y−k) 2 =r 2 . Finding the center and radius from the equation. Applications: Solving problems involving arc lengths, areas of sectors, and related concepts.
