Geometry Semester Review Dec 2024

Front

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.

Front

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.

Front

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.

Front

Define a line in geometry.

Back

A line is a straight path that has no thickness and extends infinitely in both directions.

Front

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.

Front

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.

Front

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.

Front

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.

Front

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.

Front

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.
