Answer:
The triangle DEF
Step-by-step explanation:
If we see triangle ABC then by observing then we can say BC is base, AC is perpendicular and AB is hypotenuse .
When we rotate triangle ABC counter-clock wise rotation about P then
Then base BC becomes perpendicular of triangle, AC becomes base of triangle and hypotenuse AB remains same .
We can see this process through diagram.
Hence, the final triangle we obtain after 90° rotation is look similar as triangle DEF
