Answer 1

it is isosceles triangle

Answer 2

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
