Which of the following is not part of the converse of the triangle proportionality theorem?

a. a perpendicular line to one side of a triangle. b. aa similarity theorem c. two sides divided proportionally. d. a parallel line to one side of a triangle

Option: A is the answer.

( A.   A perpendicular line to one side of a triangle )

Step-by-step explanation:

The converse of proportionality theorem states that:

" If a line divides two sides of a triangle proportionally, then that line is parallel to the third side "

Hence we are asked to find which statement is not a part of the Converse of Triangle Proportionality theorem.

The statement is:

" A perpendicular line to one side of a triangle "

Hence option A is the answer.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
