1. Oblicz, jaka wysokość ma trójkąt równoboczny o boku: a) 12 b) 5 c) √3 d) 4√6 2. Oblicz pole trójkąta równobocznego o boku: a) 8 cm b) 10 cm c) 2√3 cm d) 5√2 cm

1 a)h=12*√3:2=6√3 b)h=5*√3:2=2,5√3 c)h=√3*√3:2=1,5 d)h=4√6*√3:2=6√2 2 a)P=8²*√3:4=16√3 b)P=10²*√3:4=25√3 c)P=2√3²*√3:4=3√3 d)P=5√2*√3:4=12,5√3

1. a) 12 a = 12 h = (a√3)/2 h = (12√3)/2 h= 6√3 b) 5 a =5 h = (5√3)/2 c) √3 a = √3 h = (√3*√3)/2 h = 3/2 d) 4√6 a = 4√6 h = (a√3)/2 h = 4√6*√3)/2 h = (4√18)/2 h = 2√18 h= 6√2 2. a) 8 cm a = 8 P= (a²√3)/4 P= (8²*√3)/4 P =(64 √3)/4 P = 16√3 b) 10 cm a = 10 P = (a²√3)/4 P = (10²√3)/4 P = 25√3 c) 2√3 cm a = 2²√3 P = (a²√3)/4 P = (2√3²*√3)/4 P = 12√3/4 P = 3√3 d) 5√2 cm a = 5√2 P = (5√2²√3)/4 P = (50√3)/4
