AB is the diameter of a circle and C is any point on the circumference of a circle such that AC = BC then ∠ CAB is equal to​

Answer 1

Answer:

Answer

⇒ In △ABC,

⇒ ∠BCA=90

o

[ Angle inscribed in semi-circle ]

⇒ AC=BC [ Given ]

∴ ∠ABC=∠CAB [ Opposite angles of equal sides are equal ]

∴ ∠CAB+∠ABC+∠BCA=180

o

∴ ∠CAB+∠CAB=90

o

=180

o

∴ 2∠CAB=180

o

−90

o

∴ 2∠CAB=90

o

∴ ∠CAB=45

o
