Which best explains whether or not triangles rst and acb are congruent? the figures are congruent. δrst can be mapped to δacb by a reflection over the x-axis and a translation 2 units to the left. the figures are congruent. δrst can be mapped to δacb by a reflection over the y-axis and a translation 2 units down. the figures are not congruent. point r corresponds to point a, but s corresponds to b and t corresponds to c. the figures are not congruent. point r does not correspond with point a.

A

Well, the triangles are congruent. So we can eliminate C & D.

B is incorrect. This is because if you map triangle RST across the y-axis, it won't even be close to ABC. Even if you did move the triangle down 2 units, to wouldn't perfectly fit onto ABC.

A is correct because if you reflect it across the x-axis, RST will make the same shape as ABC. Moving it left by 2 spaces will make RST perfectly fit onto ABC.

true

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
