Question

Which is the image of ABC for a 90° counterclockwise rotation about P?

Answer 1

The answer is EFD because the turn is counterclockwise, around point P

- Your welcome

Answer 2

The triangle DEF

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
