Answer:
Hehe
Step-by-step explanation:
TAKE THAT SIDES
AB = BC = CA = a
then AD CUT BC AS
BD = CD = a/2
SO IN ∆ ADB ANGLE ADB = 90°
AB² = BD²+AD²
(PYTHAGORAS THEOREM)
(a)² = (a/2)²+AD²
( AB = a)
a². = a²/4+AD²
a²-(a²/4) = AD²
4a²-a²/4 = AD²
(LMC of 1 and 4 is 4)
3a²/4 = AD²
(cross multiplication)
3a² = 4AD²
3AB² = 4AD². --------------->hence proved
(AB = a)
