3. Kendra is wrong because 'p' is the hypotenuse.

8. If the triangle shown in the text book is a right angle than hypotenuse should be 60cm² because 20cm²+40cm² =60cm² .

11. a² + b² = c²

(6x6) + (5x5) = 8x8

36cm² + 25cm² = 61cm²

61cm² = 64cm²

-Since 61cm² does not equal 64cm² it is not a right triangle.

16. a² + b² = c²

(12x12) + (20x20) = c²

144cm² + 400cm² = 544cm²

√544cm² = 23.32cm

-Baldeep can be sure his box can be square by measuring the hypotenuse.

Nice work, Sam ! But you spelt Pythagpras wrong.

ReplyDeleteFor number 3, you could've explained further and shown your work. Add a little color to your posts, so you can catch the readers attention.

Good job Sam!! Next time you should use colors so it makes it more outstanding.
