An indirect proof of the given statement will begin with the first statement - Assume that the sum of interior angles of a figure is 180° and the figure is not a triangle. (D)
- Indirect proof is also known as proof from contradiction.
- In this method, we start by taking a statement that is false with respect to the original statement and assuming that it is true. (basically taking the opposite of what the original statement states.)
- And then we continue on with the assumption till a contradiction arises.
- In this case, statement (D) is the false statement with respect to the original statement, so the indirect proof must start with it.
