Tessellations - Colin Foster
... 360. That cannot be right, because 360 is an arbitrary number that we choose to divide a whole turn into. We could have used 100, or 2 (could mention radians here), or 359, which is prime. See sheet for an explanation of why only some polygons tessellate. Polyominoes. Obviously dominoes will tessel ...

... trigonometric functions defined by the angles of a right triangle. They also know and are able to use elementary relationships between them. For example, tan(x) = sin(x)/cos(x), (sin(x))2 + (cos(x))2 = 1. (Key) Standards 19.0 Students use trigonometric functions to solve for an unknown length of a s ...

... mpEDC + mpC. The sum of the angles of triangle ªDEC is: mpDEC + pEDC + mpC. But these sums are equal, since pDEC pADE. Thus, since the angle sum of the triangle is no more than 180, so is the sum of the summit angles. Since the summit angles are equal in measure, they must be acute. ...
