Question

3. In a circle with centre P, AB and CD are equal chords. If
angle APB = 100°, then find angle PCD.​

Answer 1

Answer:

40 degree

Step-by-step explanation:

40 degree is the answer

Answer 2

Answer:iif a circle have two equal chords the distance between the radius is equal . PB=PD( it is a radius),PA=PC(it is a radius ),angle APB=angle CPB ( vertically opposite angles ). triangle APB=triangle CPD by SAS criteria APB = PCD =100 degree (vertically opposite angles)
