8.(i) In right triangle ABC, right angled at C, M is the mid-point of hypotenuse AB. C is joined to M and produced to a point D such that . Point D is joined to point B (see Fig.). Show that:
(i)
Consider and ,
(i) (Since M is the mid-point)
(ii) (Vertically opposite angles are equal)
(iii) (Given)
Thus by SAS congruency, we can conclude that :
