Jerick873 Triangles Blog Post

This is my scribe for December 14th,2009
I had to do question #14

The question gave me 5 triangles triangle A, B, C, D, E and it gave there side lengths all i had to do is show if it is a right triangle.

Triangle (A) the side lengths are 9,12,15.
answer: 9 squared = 81, 12 squared=144 and 81+144 equals 15 squared which is 244 so it is a right triangle.

Triangle (B) the side lengths are 7,8,11.
answer: 7 squared = 49, 8 squared=64 and 49+64 does not equal 11 squared which is 121 so it not a right triangle.

Triangle (C) the side lengths are 7,24,25.
answer: 7 squared = 49, 24 squared=576 and 49+576 equals 25 squared which is 625 so it is a right triangle.

Triangle (D) the side lengths are 16,30,34.
answer: 16 squared = 256, 30 squared=900 and 256+900 does equal 34 squared which is 1156 so it is a right triangle.

Triangle (E) the side lengths are 10,11,14.
answer: 10 squared = 100, 11 squared=121 and 100+121 does not equal 14 squared which is 196 so it is not a right triangle.
