Triangle pqr lies in the xy-plane, and the coordinates of vertex q are (2, –3). triangle pqr is rotated 180° clockwise about the origin and then refected across the y-axis to produce triangle p′q′r′, where vertex q′ corresponds to vertex q of triangle pqr. what are the coordinates of q′?

(2,3)

Step-by-step explanation:

We are given that triangle PQR lies in the xy-plane, and coordinates of Q are (2,-3).

Triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R',

We have to find the coordinates of Q'.

The coordinates of Q(2,-3).

180 degree clockwise  rotation about the origin  then transformation rule

The coordinates (2,-3) change into (-2,3) after 180 degree clockwise rotation about origin.

Reflect across y- axis the transformation rule

Therefore, when reflect across y- axis then the coordinates (-2,3) change into (2,3).

Hence, the coordinates of Q(2,3).

The triangle won't exist.

Step-by-step explanation:

If the two shorter lengths add up to be shorter than the longest length, the triangle can't exist.
