2. Algebra 1 Foundations, pg 143 In the Solve It, the sailboats have the same shape but they are different sizes. Similar figures have the same shape, but not necessarily the same size. Such figures can help you measure real-world distances indirectly.  Students will be able to find missing lengths in similar figures and to use similar figures when measuring indirectly. Focus Question How can you find the missing side lengths in similar figures?  You can write and solve a proportion.

8. Algebra 1 Foundations, pg 145 A scale drawing is a drawing that is similar to an actual object of place. In a scale drawing, the ratio of any length on the drawing to the actual length is always the same. This ratio is called the scale of the drawing.  Students will be able to find missing lengths in similar figures and to use similar figures when measuring indirectly.

9. Algebra 1 Foundations, pg 145  Students will be able to find missing lengths in similar figures and to use similar figures when measuring indirectly.

10. Algebra 1 Foundations, pg 146 A scale model is a three-dimensional model that is similar to an actual three-dimensional object. The ratio of a linear measurement of a model to the corresponding linear measurement of the actual object is always the same. This ratio is called the scale of the model.  Students will be able to find missing lengths in similar figures and to use similar figures when measuring indirectly.

12.  Students will be able to find missing lengths in similar figures and to use similar figures when measuring indirectly. 6.For a celebration a town is going to pass out miniature replicas of the town’s bell. The replicas are 9 in. tall. If the scale of the replica is 1 in. : 0.5 ft, how tall is the actual bell? 7.An architect created a scale model of what a college campus will look like once construction is finished. The scale for the model is 2 in. : 25 ft. The tallest building in the model is 10 in. tall. How tall is the actual building? 8.A model of a golf course says that hole #9 is 175 yards long. If the scale of the model is 2 in. : 20 yards, how many inches are there between the tee and the hole on the model?
