Question

a geometric transformation that changes the size of a figure while keeping its shape and orientation is called
the fixed point in a plane from which all points are expanded or contracted during a dilation is called the
the ratio that determines how much a figure is enlarged or reduced during a dilation is known as the
in a dilation, the angles of the figure remain
in map - making, dilations are used to large geographical areas to fit onto smaller maps.

Explanation:

1. A dilation changes the size of a figure while keeping its shape and orientation.
2. The center of dilation is the fixed - point from which all points are expanded or contracted.
3. The scale factor determines the amount of enlargement or reduction in a dilation.
4. In a dilation, the angles of the figure remain the same (congruent) as the original figure.
5. In map - making, dilations are used to reduce large geographical areas to fit onto smaller maps.

Answer:

1. Dilation
2. Center of dilation
3. Scale factor
4. Congruent
5. Reduce
