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.
Which of these could be a step to prove that BC2 = AB? + AC?? (6 points)
Select one:
a. By the cross product property, AB? = BC multiplied by BD.
b. By the cross product property. AC2 = BC multiplied by BD.
c. By the cross product property, AC? = BC multiplied by AD. X
d. By the cross product property, AB? = BC multiplied by AD.
