Isosceles Trapezoid

Instructions:

Below, you will find an isosceles trapezoid centered at the origin (0,0). ✔️ Use the slider (a) to rotate the trapezoid between 0 and 360 degrees. ✔️ 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.

該当するものを全て選択

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