DP 2.6 Similar Polygons
Triangle DEF is a dilation of triangle ABC with scale factor 2. In triangle ABC, the largest angle measures 82o. What is the largest angle measure in triangle DEF?
41∘
82∘
180∘
164∘
What characteristics are needed to determine that two polygons are similar?
The quadrilateral PQRS in the diagram is a parallelogram. Which of the following statements would be true if P′Q′R′S′ is the image of PQRS after applying a dilation centered at a point O with scale factor 3?
P′Q′=PQ
P′Q′=3PQ
PQ=3P′Q′
Cannot be determined from the information given
Answers
A. Because changing the size of a polygon doesn't change its angles, it would stay at 82°.
B. The characteristics needed to prove they are similar are just their angles.
C. The scale factor is 3, so P'Q'=3PQ.

Answer:
The lengths of AB and EF are 10 and 2 respectively
Step-by-step explanation:
The lengths of AB and EF are 10 and 2 respectively
If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;
AB/DE = BC/EF
5x/4 = 5/x
5x² = 20
x² = 20/5
x² = 4
x = 2
Since the value of x is 2, length of AB is 5x = 5(2) = 10
Since EF = x, hence EF = 2
The lengths of AB and EF are 10 and 2 respectively

If no justification for work, you shall get reported bc of spam of points. Thank you!!
Answers
Answer:
Step-by-step explanation:
Sky High $50 = 10 people so on $5 each person
Jump it up $70 fee then $2 per person
90 for 10 people at jump it up
100 for 15 people at jump it up
75 for 15 at sky high
110 for 20 people at jump it up
100 for 20 at sky high
118 for 24 people at jump it up
120 for 24 people at sky high
the minimum number of friends for it to be cheaper at jump it up is 24 friends since it would be $118 compared to $120 at sky high
the set up fee of 70 then 2 per friend compared to 50 for 10 to start then 5 each makes it come down to 24 friends in all for jump it up to be cheaper minimum anything lower sky high is cheaper
