Is ΔDEF with vertices D(1, 4), E(6, 2), and F(−1, 3) a scalene triangle? Explain. You
must have work (not a picture) to back up
your answer.

This does not make sense

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
