Taking test ! a triangular peak on a backyard shed is trimmed with 3 pieces of 4 ft. molding. the next door neighbor decides to use 12 ft. of molding to add a decorative triangle to his shed. are the two triangles congruent? justify your answer. a) yes; both owners are using 12 linear feet of molding. eliminate b) yes; since both triangles have 3 sides, they are similar and congruent. c) yes; twelve feet divided by 3 sides always gives 4 feet for each side length. d) not necessarily; the sides of the neighbor's triangles could have different side lengths such as 3, 4, and 5.

D)not necessarily; The sides of the neighbor's triangles could have different side lengths such as 3, 4, and 5.  

Step-by-step explanation:

The perimeter of a triangle is the distance around the figure.

The original triangle has sides that are 4, 4 and 4; the perimeter is 12.

However, just because the neighbor has a triangle with a perimeter of 12 does not mean the sides are the same length.  There is a number of combinations of sides that will give us a sum of 12 and not be 4, 4 and 4.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
