Р= 9+9+7= 25 см
Треугольник можно будет построить
3
1) АВ=ВС по условию
2) угол АВД=СВД по условию
3) сторона ВД общая
Из этого следует что треугольник АВД равен ДВС по первому признаку
А из этого следует что треугольник АДС равнобедренный по признаку равнобедренного треугольника
4
1) АВ=ВС
2) АК=МС
3) треугольник равнобедренный ( судя по 1 пункту ) из этого следует что углы при основании у него равны
