Question

refer to the trapezoid in the diagram. identify a line of reflection that flips the trapezoid onto itself

Explanation:

Step1: Identify vertices' coordinates

A(-2,4), B(1,3), C(1,-1), D(-2,-2)

Step2: Check reflection over y=1

Reflect (x,y) over y=1: (x, 2 - y)

Step3: Verify vertex mappings

A(-2,4)→(-2,-2)=D; D(-2,-2)→(-2,4)=A; B(1,3)→(1,-1)=C; C(1,-1)→(1,3)=B

Answer:

y=1
