WebA chord of length 48 cm is drawn in a circle of radius 25 cm. Calculate its distance from the center of the circle. Solution: AB is the chord of the circle with centre O and radius OA OM is perpendicular to AB Therefore, AB = 48 cm OA = 25 cm OM ⊥ AB M is the mid-point of AB AM = 1/2 AB = ½ × 48 = 24 cm Now right ∆OAM, OA 2 = OM 2 + AM 2 WebmBC = 135, PD is tangent to circle O at D, PAC is a secant, and chords BD and AC intersect at E.

WebMar 24, 2024 · Here we draw the circle with the diameter AB which bisects the chord MN at P. O is the centre of the circle. We need to prove that AB bisects \[\angle MON\]. Now we have, OM and ON are the radius of the circle so these two are equal. Therefore, we get, In \[\Delta MOP\] and \[\Delta NOP\] OM=ON. OP is the common side (So, OP=OP). Web4. Theorem 4: The line that is drawn through the center of the circle to the midpoint of the chords is perpendicular to it.In other words, any line from the center that bisects a chord is perpendicular to the chord.. 5.
