rotation
Strictly speaking, the only geometric item that has neither length nor width is a "point", but as such, it is not considered a "figure". A geometric figure is defined as a "set of points". I suppose a point could be thought of as a set containing only one element, but that rather contradicts the intention of the definition where it refers to points in the plural.As Euclid defined it: A figure is that which is contained by any boundary or boundaries.
the invarient point is the points of the graph that is unaltered by the transformation. If point (5,0) stays as (5,0) after a transformation than it is a invariant point The above just defines an invariant point... Here's a method for finding them: If the transformation M is represented by a square matrix with n rows and n columns, write the equation; Mx=x Where M is your transformation, and x is a matrix of order nx1 (n rows, 1 column) that consists of unknowns (could be a, b, c, d,.. ). Then just multiply out and you'll get n simultaneous equations, whichever values of a, b, c, d,... satisfy these are the invariant points of the transformation
describe a point
A circle
A circle.You don't even need the words " ... at the center of the figure".
Rotation
Its called points maybe
a pivot
A rotation
rotation (i think)
hi my name is bill
dilations
The rule for the transformation above is translation. Translation is a transformation that moves every point of a figure the same distance in the same direction.
An enlargement with a scale factor of 0.
Transformation in maths is when you shift a point or multiple points in terms of it's original point. Ie if you were to shift the point (2;1) about the x axis the transformed point would be (-2;1).
it is a point in the middle of a figure or an object.
