ABC congruent DEF find the measure of the given angles or the lengths of the given sides

BC = 8 and EF = 8

Step-by-step explanation:

Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.

Let us solve the question

∵ The two triangles ABC and DEF are congruent

∴ BC = EF

∵ BC = 3z + 2

∵ EF = z + 6

→ Equate their length

∴ 3z + 2 = z + 6

→ Subtract z from both sides

∵ 3z - z + 2 = z - z + 6

∴ 2z + 2 = 6

→ Subtract 2 from both sides

∵ 2z + 2 - 2 = 6 - 2

∴ 2z = 4

→ Divide both sides by 2

∴ z = 2

→ Substitute z by 2 in the length of sides BC and EF to find them

∵ BC = 3(2) + 2 = 6 + 2

∴ BC = 8

∵ EF = 2 + 6

∴ EF = 8
