Answer:
A. Distance formula
Explanation:
Proving that two triangles are congruent by SSS means that we want to prove that each side in the first triangle is equal to its corresponding side in the second one.
The distance formula is the one to get you the side lengths.
Assume that we want to prove that triangle ABC is congruent to triangle DEF by SSS.
We will use the distance formula to get the lengths of:
AB
BC
AC
DE
EF
DF
Then, we will check the side length that we calculated, if we find that:
AB = DE
BC = EF
AC = DF
Then, the two triangles are congruent by SSS
Hope this helps :)

Answer:
perimeter of a rectangle = 5/2 Foot or 2.5foot
Step-by-step explanation:
from the question given that the rectangular frame has a length of 3/4
the rectangular frame has a width of 1/2 foot
perimeter of the rectangle = ?
<u>solution</u>
in order to find the perimeter of a rectangle, we need to know the value of the length and the value of the width and it has been given in the question.
the formula for finding the perimeter of a rectangle = 2L + 2W
perimeter of a rectangle = 2 ( 3/4) + 2 ( 1/2)
perimeter of a rectangle = 3/2 + 1
perimeter of a rectangle = 3 + 2/ 2
perimeter of a rectangle = 5/2 Foot or 2.5foot
Therefore the perimeter of the rectangle whose length is 3/4 foot and width is 1/2 foot is equal to 5/2 foot.
