Answer:
isosceles triangle
Step-by-step explanation:
- "the length of two tangent drawn from the external point to a circle are equal."
(it's a property of tangent)
here,
D is the common point that meets at two points on circumference of the circle.
hence,
length of DB will be equal to length of TD
& so it is isosceles triangle.
isosceles triangle means..two sides are equal
