Объяснение:
1. Периметр треугольника равен P=a+b+c
Так как AB=CD, а AB = 4, то CD=4
остальное нам дано в условии, AD=6, AC=7
получается:
P = a+b+c = 4+6+7 = 17
ответ: периметр ACD = 17
2. В равнобедренном треугольнике углы при основании равны
∠А=∠С
В равнобедренном треугольнике боковые стороны равны
АВ=ВС
Точка К- середина стороны АВ. АК=КВ
Точка М - середина стороны ВС ВМ=МС
АК=КВ=ВМ=МС⇒ АК=МС
Медиана ВD делит основание АС пополам
BD=DC
Δ AKD=Δ DMC
по двум сторонам и углу между ними
1) BD=DC
2)АК=МС
3)∠А=∠С
