Take the Chapter 5 Quiz!
6-1 and 6-2: Proportions and Similarity
1. Read 6-1 – ratios are simply another way of writing fractions.
2. Blackbeard comes across a merchant fleet. This fleet is heavily armed, with 500 cannons among its ships. Blackbeard's ships only boast 300 cannons. What is the ratio of Blackbeard's cannons to the merchants' cannons?
3. In 6-1 work problems 2, 4, 16, 26 (look back at proportions), 40, 44, 46.
4. Gunnel Sally enjoys poking around the captain's cabin while he's not there. Her favorite object is a scale model of the ship. If it's a perfect reproduction, and a 50 foot tall mast is 10 inches on the model, how wide would the captain's cabin be, if it's 10 feet wide in real life?
5. Read 6-2 – we'll use ratios to see if two polygons are similar.
6. In 6-2 work problems 4-8 even, 28, 32, 36, 52, 62, and 73.
Extra Credit: 6-1 # 23-25. 6-2 # 16, 26, and 44.
