Lesson 1: Practice Problems
Problem 1
Here is a figure that looks like the letter A, along with several other figures. Which figures are scaled copies of the original A? Explain how you know.
Problem 2
Tyler says that Figure B is a scaled copy of Figure A because all of the peaks are half as tall.
Do you agree with Tyler? Explain your reasoning.
![Two 12 sided figures in the shape of a W are labeled A and B. Both figures are composed of vertical and horizontal line segments that meet at a right angle. In figure A, the height is labeled 4 centimeters and in figure B, the height is labeled 2 centimeters. The width of both figures, appear to be the same, and is not labeled.](../../../../../../embeds/9e488ebe--7.1.PP.New.Image.01.png)
Problem 3
Here is a picture of the Rose Bowl Stadium in Pasadena, CA.
![A satellite image looking down on a stadium in the shape of an oval. The stadium is slightly wider than it is tall.](../../../../../../embeds/d8c19b19--Rose_Bowl_aerial.jpg)
Here are some copies of the picture. Select all the pictures that are scaled copies of the original picture.
Problem 4
