Isosceles  Equilateral 
(a) If she plans a scarf in the shape of an isosceles triangle with base 50 inches, how long will be the two equal sides ?
(b) If she plans the scarf to be in the shape of an equilateral triangle, then what will be the length of each side of the scarf ?

Answer 1

Answer:

a) the two equal sides will be 23 inches each

Because 96-50=46 and then since the 2 sides are equal you divide the 46 by 2 and get an answer of 23 inches

b) the length of each side of the scarf will be 32 inches

Because 96/3=32 we divide by 3 because an equilateral triangle has 3 equal sides
