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 line 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 perpendicular bisector of the bases (the two parallel sides). If we fold the isosceles trapezoid along this line, the two non - parallel sides (legs) and the two bases will match exactly. There is no other line that can divide the isosceles trapezoid into two mirror - image congruent parts.
