Question

.A quadrilateral ABCD is inscribed in a circle and
AC is a diameter of the circle, then :
(a) angleA = angleC
[b] angleD = angleA
(c) angleB = angleC
(d) angleB = angleD
plz give correct answer​

Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

refer the reference diagram uploaded above

Step-by-step explanation:

so basically here □ABCD is inscribed in certain circle and AC is its diameter

so we know that

Diameter always subtends a right angle at any point on circumference of circle

Hence Angle ABC=Angle ADC=90 Degrees

ie Angle B=Angle D=90 degrees

Hence Option (D) is ryt
