The coordinates of quadrilateral PQRS are P(0, 0), Q(a + c, 0), R(2a + c, b), and S(a, b). How can you use coordinate geometry t
Flauer [41]
We will use the formula for the slope:
m = ( y2- y1 ) / ( x2 - x1 )
For PQ : m = ( 0 - 0 ) / ( a + c - 0 ) = 0
For RS : m = ( b - b ) / ( a - ( 2a + c )) = 0
Both slopes are m = 0, so PQ and RS are parallel to x - axis and at the same time parallel to each other ( PQ | | RS ). One pair of opposite sides is parallel.

Tanya's rotation maps point K(24, –15) to K'(–15, –24). Which describes the rotation? 90 degrees clockwise rotation 270 degrees
alexira [117]

Answer:

A. 90 degrees clockwise rotation

Step-by-step explanation:

Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.

Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)

Them we will negate the new y coordinate axis to have;

K'(-15, -24)

Therefore the correct answer is 90° clockwise rotation.
