Question

the figure is an isosceles trapezoid. how many lines of reflectional symmetry does the trapezoid have? 0 1 2 3

Explanation:

Step1: Recall the definition of reflectional symmetry

A line of reflectional symmetry is a line that divides a figure into two congruent parts such that one part is the mirror - image of the other.

Step2: Analyze the isosceles trapezoid

For an isosceles trapezoid, there is only one line of symmetry. This line is the vertical line that passes through the mid - points of the non - parallel sides (the bases). If we fold the isosceles trapezoid along this vertical line, the two halves will match exactly. There is no horizontal line of symmetry (because the two bases are of different lengths) and no other oblique lines of symmetry.
