Geometric transformations are operations that alter the position, size, or shape of a figure in a plane. Common types include translation, rotation, reflection, and dilation.

Translation is a type of transformation that slides a figure from one position to another without changing its shape, size, or orientation.

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Dilation is a transformation that changes the size of a figure but keeps its shape the same, using a scale factor.

Congruent means that two figures have the same size and shape.

A polygon is a closed figure made up of straight line segments. Examples include triangles, quadrilaterals, and pentagons.

A right triangle is a triangle that has one angle measuring 90 degrees.

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

A composite number is a whole number greater than 1 that has more than two distinct positive divisors (factors).
