Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.
А
B
С
Which of these could be a step to prove that BC2 = AB? + Ac?? (6 points)
By the cross product property, ABP = BC multiplied by BD.
Ob By the cross product property, AC2 - BC multiplied by BD.
By the cross product property, Ac? = BC multiplied by AD.
Od By the cross product property, AB? = BC multiplied by AD.

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph

93-8=85

855=17

17*4=68
