In Fig. 10.19, AB and CD are two chords of a circleintersecting each other at point E. Prove that∠AEC =1/2 (Angle subtended by arc CXA at centre+ angle

1/2 (angle AOC) = angle ADE ..1 (Angle at the center is double the angle at other part made by arc) 1/2 (angle BED) = angle DAE ..2 (using same property as above) angle AEC = angle ADE + angle DAE (Exterior angle equal to the sum of opposite interior angle in Δ) angle AEC =1/2(angle AOC + angle BED) [using 1 and 2] angle AEC =1/2(angle subtended by arc CXA at center + angle subtented by arc DYB at the center) Hence, proved
