Question

in the figure, find perimeter of ∆ABC, if AP = 10 cm​

Answer 1

Answer:

Perimeter = 20 cm

Step-by-step explanation:

The length of tangents from an external point are equal.

Therefore, AP = AQ

Similarly, BR = BP and CR = CQ

Perimeter of triangle ABC = AB + BC + AC

= AB + BR + CR + AC

= AB + BP + CQ + AC

= AP + AQ

= AP + AP

= 10 + 10

= 20 cm
