By definition, two shapes are congruent if you can map one onto the other using rigid transformations (a sequence of one or more rotations, translations, and reflections). since any sequence of rigid transformations performed on a triangle results in a congruent triangle, what does that imply about the corresponding side lengths and angle measures for two congruent triangles?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
