4. Prove that theperpendicular drawn,to the base of an isosceles trian

1.	4. Prove that theperpendicular drawn,to the base of an isosceles triangle from the vertex bisects the base
Answer» U can use RHS congruence rule.In ∆ADB and ∆ADCangleADB=angleADC=90° (since AD is perpendicular to BC) AB=AC( since it is an isos triangle)AND. AD=AD (common)therefore the triangles are congruent. BD=DC(by cpct)
