Triangle ABC, with vertices A(3, 0), B(2, 4), and C(4, 2), undergoes a transformation to form triangle A′B′C′, with vertices A′(
3, 0), B′(2, -4), and C′(4, -2). The type of transformation that triangle ABC undergoes is a . If triangle A′B′C′ undergoes a transformation to form triangle A″B″C″, with vertices A″(-3, 0), B″(-2, -4), and C″(-4, -2), then the type of transformation that triangle A′B′C′ undergoes is a .
When Sam is 13 his mother will be 39 which is 3 times as old as he is. So Sam's mother will be 3 times as old as Sam will be in 11 years. (Your answer is 11 years.)
