M2 Scale Factor and Transformation Review

Front

What is the scale factor from a smaller figure to a larger figure?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures.

Front

If a scale drawing uses a scale of 1 inch = 2 feet, how do you convert real-life measurements to the drawing?

Back

To convert real-life measurements to the drawing, divide the real-life measurement by the scale factor.

Front

What is the term for the original figure before a transformation?

Back

Pre-Image

Front

How do you find the length of a room in a scale drawing if the real-life length is known?

Back

Multiply the real-life length by the scale factor.

If a scale drawing car length is 3 cm and the scale is 1 cm:4 ft, what is the actual car length?

Back

12 feet

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the types of transformations?

Back

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

Front

What does dilation mean in the context of transformations?

Back

Dilation is a transformation that changes the size of a figure but not its shape.

Front

How do you calculate the scale factor between two similar figures?

Back

The scale factor is calculated by dividing the length of a side of the image by the length of the corresponding side of the pre-image.

If a backyard is 78 feet long in real life and the scale is 1 inch = 2 feet, how long is it in the drawing?

Back

39 inches
