What are three basic aplications of congruency and similarity
mark as brainlist who gives answer

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion

Step-by-step explanation:

10.8 kilometers

Step-by-step explanation:

t = 15 min = 15*60 = 900 s

v = 12 m/s

d = the distance

d = v*t

d = 12*900

d = 10,800 m

d = 10.8 km (since 1 km = 1,000 m)

In 15 minutes you go 10.8 kilometers.
