Front

What is the rule for translating a point 3 units up and 2 units to the right?

Back

(x, y) → (x + 2, y + 3)

Front

What is the angle of rotational symmetry for a shape with an order of 3?

Back

120°

Front

What is the order and angle of rotation for a flower with order 6?

Back

Order 6, 60 degrees

Front

How do you find the order of rotational symmetry in a shape?

Back

Count the number of times the shape fits onto itself during a full rotation.

Front

What is the translation of triangle ABC to triangle A'B'C' if it moves right 4 and down 9?

Back

right 4, down 9

Front

Define rotational symmetry.

Back

A shape has rotational symmetry if it can be rotated around a center point and still look the same at certain angles.

Front

What is the formula for translating a point (x, y) up by k units?

Back

(x, y) → (x, y + k)

Front

What is the formula for translating a point (x, y) down by k units?

Back

(x, y) → (x, y - k)

Front

What is the formula for translating a point (x, y) left by k units?

Back

(x, y) → (x - k, y)

Front

What is the formula for translating a point (x, y) right by k units?

Back

(x, y) → (x + k, y)
