Similar Figures

The video lesson covers the concept of similar figures, focusing on identifying corresponding sides and angles, and using proportions to determine similarity. It explains the difference between similar and distorted images, and includes exercises to find similar rectangles and solve for missing measurements. A real-world problem involving image enlargement is also discussed.

What is the main question to consider when determining if two figures are similar?

• How can you use a proportion to determine if two figures are similar?

• What is the area of the figures?

• What is the perimeter of the figures?

• Are the figures congruent?

Which of the following is true about similar figures?

• They have proportional corresponding sides.

• They have different angles.

• They have different shapes.

• They have congruent corresponding sides.

What symbol is used to denote similarity between figures?

• A minus sign

• An equal sign

• A squiggly line

• A plus sign

What happens when you resize an image by dragging only one side?

• The image remains similar.

• The image becomes distorted.

• The image becomes smaller.

• The image becomes larger.

How can you ensure an image remains similar when resizing on a computer?

• Drag from the side of the image.

• Drag from the top of the image.

• Drag from the bottom of the image.

• Drag from the corner of the image.

Which pair of rectangles was found to be similar in the exercise?

• Rectangles A and C
