There are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8
Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.
Because these triangles are similar, a simple ratio may be set up in order to calculate DE.
DE / AC = EA / AB
DE = 3/6 * 8
DE = 4 units

Answer:

here are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8

Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.

Because these triangles are similar, a simple ratio may be set up in order to calculate DE.

DE / AC = EA / AB

DE = 3/6 * 8

DE = 4 units
