1. What must be true in order for triangles DEF and ABC to be similar? Be very specific about the properties of the angles and sides of these two triangles.
с
F
A
B
D
E

Answer/Step-by-step explanation:

For ∆ABC and ∆DEF to be similar the following must be true:

1. ∠A ≅ ∠D

2. ∠B ≅ ∠E

3. ∠C ≅ ∠F

4. The ratio of the length of their corresponding sides must be equal and proportional.

That is:

If all these are true, then ∆ABC ~ ∆DEF, because the corresponding angles of two similar shapes are equal, while the ratio of their corresponding side lengths are equal.

i think the answer is a p = 78

step-by-step explanation:

there are 6 sides of a hexagon, multiply 13 x 6

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
