using geometry**
- Like line segments, ray XY, angles etc

please don't answer with (n-2)180 formula.

answer related to proving by lines and angles
like - <ABC + <BCA + <CAB = 180° etc...​

Answer 1

Explanation:

The answer is that yes it is because a pentagon has three triangles inside it and a triangle is equal to 180 degrees so you times 180 times three and you get 540 degrees so yes that is correct!
