Question

analyzing the symmetry of trapezoids. which statements are true regarding the symmetry of the isosceles trapezoid? choose three correct answers. the trapezoid has rotational symmetry of order 2. the trapezoid has 1 line of reflectional symmetry. the trapezoid has rotational symmetry of order 1. the trapezoid has 2 lines of reflectional symmetry.

Explanation:

Step1: Understand rotational symmetry

Rotational symmetry of order 1 means the shape looks the same only after a full 360 - degree rotation. All shapes have rotational symmetry of order 1. An isosceles trapezoid does not look the same after a 180 - degree (order 2) rotation, so it has rotational symmetry of order 1.

Step2: Analyze reflectional symmetry

An isosceles trapezoid has 1 line of reflectional symmetry which is the line that passes through the mid - points of the non - parallel sides.

Answer:

The trapezoid has 1 line of reflectional symmetry.
The trapezoid has rotational symmetry of order 1.
