The correct alternative is 4.
You are watching: Which transformation will map an isosceles trapezoid onto itself?
Step-by-step explanation:
The no parallel political parties of an isosceles trapezoid are congruent.
The picture of one isosceles trapezoid is same as the preimage the isosceles trapezoid if
1. Reflection throughout a line joining the midpoints the parallel sides.
2. Rotation through 360° about its center.
3. Rotation by 360° around origin.
If we rotate the trapezoid by 180° about its center, climate the parallel sides will interchanged.
If we reflect the trapezoid throughout a diagonal, then the resultant figure will be a parallelogram.
If we reflect throughout a line joining the midpoints that the nonparallel sides, climate the parallel sides will certainly interchanged.
After rotation through 360° around the center, we always get an top top figure.
Therefore alternative 4 is correct.

starrkingschool.net: The starrkingschool.net is (d) rotation by 360° about its centre.
Step-by-step explanation: As shown in the fastened figure, abdominal muscle and CD are parallel political parties of an isosceles trapezoid ABCD v centre "O" and advertisement and BC space equal and also non-parallel sides.
(i) If ABCD is rotated by 180° about its centre, then the new figure will certainly not coincide with the initial one. So, this choice is not correct.
(ii) If ABCD is reflected throughout a diagonal, then likewise the new figure will be reverse of the initial one and so this option is additionally incorrect.
(iii) If ABCD is reflected throughout a heat joining the mid-points of the non-parallel sides, then likewise the two numbers will be opposite of each other. This choice will additionally not work.
(iv) If we rotate ABCD through 360° around centre "O", the both the numbers will coincide v each other.
Thus, the correct option is (d) rotation by 360° about its centre.
