4. ABC is an isosceles triangle with and is one of its altitudes (Fig 7.34).
(i) State the three pairs of equal parts in and .
(ii) Is ? Why or why not?
(iii) Is ? Why or why not?
(iv) Is ? Why or why not?
i) Given in and .
( Common side)
ii) So, by RHS Rule of congruency, we conclude
iii) Since both triangles are congruent all the corresponding parts will be equal.
So,
iv) Since both triangles are congruent all the corresponding parts will be equal.
So,
.
