Kim performed a transformation on rectangle ABCD to create
rectangle A'B'C'D', as shown in the figure below:
What transformation did Kim perform to create rectangle
A'B'C'D'?
Rotation of 270 degrees counterclockwise about the origin Reflection across the line of symmetry of the figure Reflection across the y‐axis Rotation of 90 degrees counterclockwise about the origin
From, UV and WZ are parallel
Line ST intersecting both at points Q and R respectively.
Angle ∠SQU and ∠RQV
Vertical Angle: The angles opposite each other
when two lines cross. They are always equal.
"Vertical" refers to the vertex (where they cross), NOT up/down.
They are also called vertically opposite angles.
So, Angle ∠SQU and ∠RQV are Vertical
angles.
