Answer:
Length: 6 ft
Width: 4 feet
Step-by-step explanation:
Length: L
Width: 2L - 8
2L + 2(2L - 8) = 20
2L + 4L - 16 = 20
6L = 36
L = 36/6
L = 6
W= 2(6)-8 = 4
Answer:
CPCTC - Corresponding Parts of Congruent Triangles are Congruent
Step-by-step explanation:
When two triangles are congruent, this means they have the same shape and the same size. To have the same shape, each angle must be congruent. To have the same size, each side length must be congruent. When you know two triangles are congruent you can say each corresponding part of congruent triangles is congruent. This is known as CPCTC.
