ABC is an isosceles triangle with AB = AC and AD is one of its altitudes.i) State the three pairs of equal parts in ΔADB and ΔADC.ii) Is ΔADB = ΔADC ? Why or why not ?iii) Is ∠B = ∠C ? Why or why not ?

Answer»

i)) ∠ADB = ∠ADC Right angle

AB = AC hypotenuse; AD = AD common side

ii) Yes,

by R.H.S congruence

iii) Yes
