A regular pentagon with a perimeter of 21 inches is dilated by a scale factor of 53 5 3 to create a new pentagon. What is the pe
2 answers:
Answer:
The perimeter of the new pentagon is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z------> the scale factor
x-----> the perimeter of the dilated pentagon
y-----> the perimeter of the original pentagon
so
we have
substitute and solve for x

Answer:
SAS theorem
Step-by-step explanation:
If and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.
So, and m∠ECD = m∠BCA because vertical angles are congruent
Therefore ΔECD is similar to ΔBCA by SAS theorem
