Presentation Transcript

### Skills Check

### Classwork describe the rotation that map the figure onto itself.

### Homework describe the rotation that map the figure onto itself.

Warm up

- A function is even. Point A(-3, 4) is on the even function. Name another point.
- A function is even. Point B(9, 2) is on the even function. Name another point.
- Reflect C(-5, -3) over the y-axis.
- Reflect D(2, -4) over the x-axis.
- Reflect E(-12, 4) over y = -x.

(3, 4)

(-9, 4)

C’(5, -3)

D’(2, 4)

E’(-4, 12)

Are you ready?

Rotate 90 Clockwise about the Origin(Same as 270 Counterclockwise)

Change the sign of x and switch the order

Rotate 90° clockwiseabout the origin

Rotate 90° clockwiseabout the origin

Rotate 90 Counterclockwise about the Origin(Same as 270 Clockwise)

Change the sign of y and switch the order

Rotate 90° counterclockwiseabout the origin

Rotate 90° counterclockwiseabout the origin

Rotate 180about the Origin

ONLY Change the signs

Rotational Symmetry

Any figure that can be turned or rotated less than 360° about a fixed point so that the figure looks exactly as it does in its original position.

Ambigrams – Look the same right side up and upside down

Which figures have rotational symmetry? For those that do, describe the rotation that map the figure onto itself.

Regular pentagon

Rhombus

Isosceles triangle

NO

NO
