During geometry class, students are told that δtsr ≅ δusv. marcus states that δtsr is mapped to δusv by performing a rotation about point s. sam states that δtsr is mapped to δusv by a reflection across the line that goes through point s. determine if either student is correct. marcus is correct. sam is correct. both students are correct. neither student is correct.

Both students are correct.

Explanation:

In rotation a shape is rotated about a fixed point and it does not affect its measurements. it only changes its position.

Now, When Marcus rotated the  about point S then this process did not affect its shape and size this is why he got the which is congruent to the .

In reflection, when a shape reflected across a line then its all points get reflected across this line. But it also does not affect the measurement of the shape.

So, when Sam mapped by the reflection of then the measurement of the did not change. And, he also got the congruent triangle.

Thus, we can say that, Both Marcus and Sam are right.
