The Challenge:

You're creating a border design for your art project. You have a triangle shape and want to create a repeating pattern. How can you use translation, rotation, and symmetry to make a beautiful border?

Art Design Challenge

Transformation Solutions:

Translation: slide triangle to the right
Rotation: turn triangle 180 degrees
Symmetry: flip triangle over a line
Repeat to create a pattern

Transformation Types Guide

Translation (Sliding):

Move without turning

Slide shape left, right, up, or down

Same size and shape

Shape stays exactly the same

Examples

Moving furniture, sliding doors

Rotation (Turning):

Turn around a point

Rotate 90°, 180°, or 270°

Same size and shape

Shape stays exactly the same

Examples

Clock hands, spinning wheels

Symmetry (Mirror):

Mirror image

Two halves that match exactly

Line of symmetry

Fold line where halves match

Examples

Butterfly, heart, letter A

Practice Examples

Translation Examples:

Slide triangle 3 units right

Move square 2 units up

Shift circle 4 units left

Rotation Examples:

Turn square 90° clockwise

Rotate triangle 180°

Turn rectangle 270°

Symmetry Examples:

Butterfly: 1 line of symmetry

Square: 4 lines of symmetry

Heart: 1 line of symmetry
