Question

AB and CD are equal chords of a circle with center P . if angleAPB =80° then find angleCPD​

Answer 1

Answer:

80

Step-by-step explanation:

we know that equal chords make equal angles at centre

Answer 2

Answer:

${80}^{o}$

Step-by-step explanation:

AB=CD

PB=PA=PC=PD= Radius

In ∆APB & ∆CPD

AB=CD

BP=CP

AP=PD

:. ∆APD ~=∆CPD (SSS)

so, /_APB = /_CPD (CPCT)

/_CPD= 80° Ans.
