HELP 5 STAR + THANKS What series of transformations from △ABC to △DEF shows that △ABC≅△DEF ? a reflection across the y-axis
followed by a translation of 1 unit right and 2 units up a clockwise rotation of 90° about the origin followed by a translation of 4 units right and 4 units up a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down a reflection across the line y = x followed by a positive rotation of 270° about the center
In the given triangle, the verteces are A(-4, 1), B(-6, 5), C(-1, 2). A refrection across the x-axis will result in A'(-4, -1), B'(-6, -5), C'(-1, -2) A translation of 1 unit to the right will result in A"(-3, -1), B"(-5, -5), C"(0, -2) A translation of 1 unit down will result in A"'(-3, -2), B"'(-5, -6), C"'(0, -3) which corresponds to points DEF. Therefore, the series of transformation required to transform ABC to DEF are <span>a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down.</span>
The error is that the student measured the wrong side. Acute angles are less than 90 degrees. So it isn’t possible for the measure to be over 90. The correct measure is 49
