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.**
