in triangle ABC, AD is the perpendicular bisector of BC. show that triangle ABC is an isosceles triangle in which AB = AC. |
|
Answer» Step-by-step EXPLANATION: AD is PERPENDICULAR bisector i.e. BD = DC and ANGLE ADB = angleADC = 90° Taking ∆ADB and ∆ADC BD = DC angle ADB = angleADC = 90° AD = AD (common) By S.A.S congruence rule, ∆ADB and ∆ADC are congruent triangles i.e. AB = BC HENCE,∆ABC IS AN ISOSCELES TRIANGLE.
