# 6, 9, 12 and 15
6. Determine the length of the leg for each right triangle.
a)
a2 + b2 = c2
72 + 252 = c2
49 + 625 = c2
674 =c2
The square root of 674cm = c2
25.96 cm = c
b)
T2 - S2 = R2
262 - 242 = R2
676 - 576 =R2
100 = R2
10cm = R2
9. Tina wants to construct a path along the diagonal of her yard. What length will the path be? Express your answer to the nearest tenth of a meter.
a2 + b2 = c2
62 + 122 = c2
36 + 144 = c2
180 = c2
The square root of 180 = c2
13.41 = c
12. The hypotenuse of the triangle cuts the circle in half. What is the diameter of the circle?
a2 + b2 = c2
72 + 52 = c2
49 + 25 = c2
74 = c2
The square root of 74 = c2
8. 60
15. The coordinate grid shown was drawn centimeter grid paper. What is the length of lime segment AB?
A and B segment looks like a right triangle.
a2 + b2 = c2
22 + 42 = c2
4 + 16 = c2
20 = c2
The square root of 20 = c2
4.47 = c
Special thanks to Anabelle for helping me out (:
Thanks.
Good job, Trisha! I liked all the colours. You're pictures helped a lot, but I didn't understand the way you found the answer to 15 because this part confuses me, "22 + 42 = c2". I don't get how you got that.
ReplyDeleteGreat post Trisha, with help from Anabelle. Your post looks very organized and you used the colors well. Your pictures were also great. Next time add a video and a link to make your post better. Other than that, great job.
ReplyDeleteGreat post, Trisha! Your post looks quite organized with the pictures, and you used a good amount of colors so it won't be distracting as much. Next time, you should add a video and a link to enhance you scribe. Nonetheless, good job!
ReplyDeleteGood job, Trisha! You stated the questions clearly, but next time consider adding a link.
ReplyDeleteGreat job Trisha and Anabelle for helping her. I liked that you have the answers for the question with details for some of them. I think one thing that can help is the squared sign (5²) and square root √. Also for some of your pictures you have a capital letter for a label it should always be lower case.
ReplyDeleteGood post Trisha and good job Anabelle for helping her! I liked how you showed your work for each question. Next time, maybe try to add a video or link.
ReplyDeleteGreat post Trisha. I liked the pictures that you added and it is all so neatly organized. I like that you changed the colour of the questions but would have preferred something brighter than brown.
ReplyDeleteGreat job, Trisha. I liked how it was neat and organized using pictures. Well done for Anabelle for helping her on her post. Next time, add a video and a link. Other than that, good job.
ReplyDeleteJulibella, I mean 2 x2 = 4 and 4 x 4 = 16. Sorry I forgot to make it lowercase.
ReplyDeleteVery Nice post Trisha, I like the pictures you added and how the things are so easy to read BUT next time add a link and a video
ReplyDeleteGood Post, adding a video would have been helpful.
