Question

Paul observes that AB=AC and concludes that AB abd AC must be tangent to the circle. What is wrong with pauls reasoning?

Answer 1

The answer should be C

Explanation:

we know that

the triangle AOB is congruent with triangle AOC

because

AB=AC

OB=OC-----> the radius of the circle

The OB side is common

but

there is no additional information that allows me to calculate the OBA angle to determine if it is a right angle

therefore

the answer is the option

C.There is no indication that AB and AC are perpendicular to the radii at the points of intersection with the circle.
