What is a transformation of a shape?
A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.
From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.
Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.
If the geometry is rotated, then there is no change in angles.
The trapezoid ABCD is rotated 90° counterclockwise about the origin.
Then point A will correspond to the top most point will be A'.
The diagram is shown below.
