Question

Please help, Fan and Medal!
Which postulate can be used to prove the two triangles below are similar? Explain your answer using complete sentences, and provide evidence to support your claims.

Answer 1

@hartnn

Answer 2

The angles are congruent so the sides wil be in a ratio

Answer 3

Since you know the two triangles are similars angle a is 41
angle b is 56 and angle c is 83

Answer 4

You can do one last check to make sure that is correct. you know that there is 180 degrees in a triangle. So 41+56+83=180
180=180

Answer 8

Sheila has 3 strips of unfinished molding that she wants to use to frame the two pictures. Each strip is 36 inches long.

Assuming there is no wastage or overlap of molding, what is the minimum length of molding, in inches, Sheila still requires to frame both the pictures? Show your work and explain your reasoning in complete sentences.

Answer 9

Ok so it is in a ratio of 37.5/25 =x/32

Answer 10

x=48

Answer 11

To frame a picture we need the perimeter.

Answer 12

So for the bigger one the perimeter=2(37.5+48)
and for the smaller one p=2(25+32)

Answer 13

bigger one p=171inches
smaller one p=114 inches

Answer 14

now add it up

Answer 15

171+114=285

Answer 16

So the minimum amount is 285 inches
