Answer: the correct option is option c
Step-by-step explanation:
The altitude rule is expressed as
left/altitude = altitude/right
The left side of the triangle ABC is AD while the right side of triangle ABC is BD. The altitude of triangle ABC is CD
The altitude rule becomes
AD/CD = CD/BD
The leg rule is expressed as
hypotenuse/leg = leg/part
The hypotenuse of triangle ABC is AB.
Firstly
The leg of triangle ABC is AC
The part of triangle ABC is AD
The leg rule becomes
AB/AC = AC/AD
Secondly
The leg of triangle ABC is CB
The part of triangle ABC is BD
The leg rule becomes
AB/CB = CB/BD
Therefore, the ratio that would not be involved in the altitude or leg rule is AB/AD = AD/BC
