Question

Choose two transformations that could have been performed on triangle JKL to form congruent triangle J"K"L".

A. Triangle JKL was rotated 90° counterclockwise around the origin to form triangle JꞌKꞌLꞌ.
B. Triangle JKL was rotated 270° clockwise around the origin to form triangle JꞌKꞌLꞌ.
C. Triangle JꞌKꞌLꞌ was reflected across the y-axis to form triangle JꞌꞌKꞌꞌLꞌꞌ.
D. Triangle JꞌKꞌLꞌ was reflected across the x-axis to form triangle JꞌꞌKꞌꞌLꞌꞌ.

Answer 1

Triangle JKL was rotated 90° counterclockwise and then refrected across the line y = -4.
