3.1 Practice - Transformations, Parallel and Perp Lines

Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected.

Front

How do you identify a reflection transformation?

Back

A reflection transformation can be identified by the symmetry of the original figure and its image across a line.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating the steepness and direction of the line.

Front

What is the slope of the line y = 1/3x - 2?

Back

The slope of the line y = 1/3x - 2 is 1/3.

Front

What is the y-intercept of the line y = 1/3x - 2?

Back

The y-intercept of the line y = 1/3x - 2 is -2.

Front

What is a parallel line?

Back

Parallel lines are lines in a plane that never meet and have the same slope.
