Consider the given figure. We will find the perimeter of â–łABC.
If two tangent segments to a circle share a common endpoint outside the circle, then the two segments are congruent. Using this fact, we can find the unknown lengths on the triangle.
Finally, we can find the perimeter of â–łABC by adding all the side lengths.
P&= 2+ 2+ 3+ 3+ 5+ 5
P&=20
