Move each point with the coordinates (a, b) to the location (b, -a).Equivalently, if the points are represented by a 2x1 column matrix, then pre-multiply by the matrix

Why can only some shapes tessellate?
Shapes can tessellate only if a number of them can meet at a point and cover 360 degrees without overlap. For regular shapes this requires that the angles of the shape are a factor of 360 degrees. For non-regular shapes it is necessary that the angles of the shapes can be grouped so that they sum to 360 degrees.
How do you work out rotation of shapes?
You can work out the rotation of shapes by identifying the transformations and the rotations.Ê The measurements of the rotation of shapes are expressed in degrees.
What is a true statement about transformations?
Transformations can translate, reflect, rotate and enlarge shapes on the Cartesian plane.
Why do you get circle shape if you rotate any shapes?
A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.
What do the exterior angles of shapes add up to?
The exterior angles of polygon shapes add up to 360 degrees

What angles are isometric shapes drawn at?
Isometric drawings and shapes are angled to 30 degrees.
What are degrees?
Degrees are measuring units of shapes, such as circles.See link below.

Why do some shapes tile and some shapes don't?
some shapes tile and some don't because if the side angles don't equal a factor of 360 degrees it will not tile and if the side angles do equal a factor a 360 degrees it willtile.
What do the exterior angles of shapes add up to?
The exterior angles of polygon shapes add up to 360 degrees
How many degrees is a parallelogram?
All 4 sided shapes each equal to 360 degrees in angles
Why do shapes have different degrees?
they have different degreeses because a different degrees is what make different types of shape
