### Diana's Pythagoras Scribe Post

Homework for the weekend : Pages 91-94 #1-21

My homework was questions : 3, 8, 11, & 16

3. Kendra wrote the Phythagorean relationship as r2= p2 + q2. Is she correct ? Explain.

Kendra is incorrect. Leg2 + leg2 = hypotenuse2. Since the legs are r and q and the hypotenuse is p, It should be r2+q2=p2 or q2+r2=p2.

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

The triangle is not a right triangle. For this triangle to be a right triangle, the area of the two smaller squares must equal the area of the larger one. Because a + b = 60 not 50.

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

It is not a right triangle since the sum of the areas of the two smaller squares aren't equal to the larger square. (6x6)= 36cm2 , (5x5)= 25cm2, 36+25=61. 61 doesn't equal 64.

16. Baldeep is building a wooden box for storing coloured 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.

A2 + B2 = C2 ,
(12x12)+(20x20)= C2,
144cm2 +400cm2= C2,
544cm2= C2.
The box with be 544cm2.
