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.
