Triangle ABC with coordinates A(-2, 5), B(-2, -2), and C(3, 5) is reflected over the y-axis. A'B'C' is then rotated 90 degrees clockwise about the origin. What is the coordinate of A"?

Describe the application of transformations in the field of fashion and textile design.

• Transformations are used to develop software and computer programs

• Transformations are used to create music and sound effects

• Transformations are used to create patterns, prints, and designs for clothing and fabrics.

• Transformations are used to design buildings and architecture

Identify the transformation:

• Reflection across y-axis

• Translation 5 units left, 1 unit up

• Reflection across x-axis

• Translation 5 units right, 1 unit down

Reflect the point in the x-axis followed by the y-axis.

• (-1.5,-4)

• (1.5,4)

• (1.5,-4)

Describe a sequence of transformations that maps figure A onto figure B.

• A translation 4 units right followed by a reflection across the x-axis
