Verified Answer :

The angle formed by the tangent AB and the radius AO of the circle is

90°.

Response:

  • The type of triangle that is always formed when points A, B and O, are connected is; a. right

How can the type of triangle formed by the tangent be determined?

The given parameters are;

AB = A tangent to the circle

Point at which the tangent AB intersects the circle = Point A on the circumference of the circle

Required:

The type of triangle formed when the points A, B and O are connected.

Solution;

The center of the circle, used to describe the location of the circle is point O.

The line OA from the center to the circumference = The radius of the circle

By the properties of a tangent line to a circle, we have;

Angle formed between the radius and the tangent of a circle = 90°

Therefore;

∠OAB in ΔOAB = 90°

Which gives;

ΔOAB formed by the connecting the points A, B, and O, is a right triangle, by definition of right triangles,

The correct option is a. right
