Isosceles Trapezoid

Instructions:

Below, you will find an isosceles trapezoid centered at the origin (0,0). [br][br]✔️ Use the slider (a) to rotate the trapezoid between 0 and 360 degrees.[br]✔️ Use the check boxes and sliders (m, b, α, and β) to explore the line(s) of reflection of the pre-image trapezoid.

Specify the lines of reflection (symmetry) for the trapezoid.

A reflection along a horizontal line passing through the trapezoid. A reflection along a horizontal line passing through the center of the trapezoid. A reflection along a vertical line passing through the trapezoid. A reflection along a vertical line passing through the center of the trapezoid.

What is the minimum angle of rotation to map the trapezoid onto itself?

Which of the choices below describe the type of types of symmetry this figure has?

Both reflectional and rotational symmetry Rotational symmetry Neither reflectional or rotational symmetry Reflectional symmetry
