Question

triangle abc was translated to form abc. which describes the transformation? select three options. ☐ it is rigid. ☐ it is nonrigid. ☐ it is isometric. ☐ the size is preserved. ☐ the angles are not preserved.

Explanation:

1. Rigid Transformation: A translation is a rigid transformation because it preserves the shape and size of the figure. So "It is rigid" is correct.
2. Isometric Transformation: Translations are isometric (distance - preserving) transformations. So "It is isometric" is correct.
3. Size Preservation: In a translation, the size (side lengths, area, etc.) of the figure is preserved. So "The size is preserved" is correct.
4. Non - rigid Transformation: A non - rigid transformation changes the size or shape of the figure. Since translation does not do this, "It is nonrigid" is incorrect.
5. Angle Preservation: In a translation, the angles of the figure are preserved (because it is a rigid transformation). So "The angles are not preserved" is incorrect.

Answer:

• It is rigid.
• It is isometric.
• The size is preserved.
