Which statement best explains whether △pqr is congruent to △xyz? △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a rotation of 180° about the origin. △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a translation 5 units down followed by a reflection across the y-axis. △pqr is not congruent to △xyz because there is no sequence of rigid motions that maps △pqr to △xyz. △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a reflection across the y-axis followed by a reflection across the x-axis.

△PQR is not congruent to △XYZ because there is no sequence of rigid motions that maps △PQR to △XYZ.

Step-by-step explanation:

We can see from the diagram that XYZ is not the same size as PQR.  This means there is no series of rigid motions, which preserve segment length, that maps PQR to XYZ.

sorry, can't i suggest going to algebra.com

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
