Angel's Pythagoras Scribe Post

Scribe 3: Pg 91-93 #3, 8, 11, 16

3. For the triangle shown, Kenda wrote the Pythagorean relationship as r2 = p2 + q2. Is she correct? Explain.














She's not correct because the right formula would be q2 + r2 = p2 because the longest line is labeled p2 which is opposite from the right angle which makes it the hypoteneuse.










8. Is the triangle shown a right triangle? Explain your reasoning.



















No, because in this case a + b doesn't equal to 50. a + b = 60







11. The side lenghts of a triangle are 5cm, 6cm, and 8cm. Determine whether the triangle is a right triangle. Explain.








16. Baldeep is building a wooden box for storing colored pencils. The box will have rectangular sides that are 12 cm wide and 20 cm long. Show how Baldeep can be sure the sides are rectangular, without using a protractor.
