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?

Corresponding side lengths and angle measures of two congruent triangles are also congruent.

Step-by-step explanation:

If two triangles ABC and DEF are congruent (see below figure) to each other then, AB=DE, BC=EF, AC=DF and <A=<D, <B=<E, <C=<F

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
