What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape. Common transformations include translations, rotations, reflections, and dilations.

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape. It involves a scale factor that determines how much the figure is enlarged or reduced.

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it.

What is a congruence statement?

Back

A congruence statement is a mathematical statement that indicates that two geometric figures are congruent, meaning they have the same shape and size.

What does it mean for two angles to be corresponding?

Back

Corresponding angles are pairs of angles that are in the same relative position at each intersection where a straight line crosses two others.

What is the difference between a point, line, and plane?

Back

A point is a location with no size, a line is a straight path that extends infinitely in both directions, and a plane is a flat surface that extends infinitely in all directions.

What is the purpose of a transformation in geometry?

Back

Transformations are used to manipulate shapes and figures to understand their properties, relationships, and to solve geometric problems.

What is the result of rotating a figure 90 degrees?

Back

Rotating a figure 90 degrees turns it around a fixed point, changing its orientation but not its size or shape.

How do you identify corresponding parts of congruent triangles?

Back

Corresponding parts of congruent triangles can be identified by matching the vertices of the triangles based on their congruence statement.
