Triangles POR and XYZ are congruent, as shown. Which sequence of transformations proves that triangle PQR is congruent to triangle XYZ using congruence criteria ASA? A. Translate POR so that Raligns with Z, and then reflect the result across PQ. B. Reflect PQR across a horizontal line through R, and then translate the image so Raligns with Z. C Reflect POR across a vertical line through R, and then translate the image so PQ aligns with XY. D. Translate POR so that Paligns with X, and then reflect the result across a horizontal line through the image of R. E. Rotate PQR by 180° counterclockwise around the point R, and then translate so that the image of P aligns with X.

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
