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.
What is an acute angle shaped like?
an acute angle is always less the 90 degrees. its different shapes depending on the number of degrees. example would be this symbol on a keyboard: <
What are 3 attributes of a quadrilateral?
It has 4 sides Its 4 interior angles add up to 360 degrees It can have different shapes.
Why are the shapes and widths of the time zones different?
The widths all average out the same ... 15 degrees of longitude per time zone. The shapes are drawn the way they are in order to avoid splitting cities and states into two different time zones.
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.
