Which best explains why all equilateral triangles are similar?

a. all equilateral triangles can be mapped onto each other using dilations.

b. all equilateral triangles can be mapped onto each other using rigid transformations.

c. all equilateral triangles can be mapped onto each other using combinations of dilations and rigid transformations.

d. all equilateral triangles are congruent and therefore similar, with side lengths in a 1: 1 ratio.

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
