Question

P(-3,4), Q(-1,4), R(-2, 1), S(-4, 1)180° about vertex R

Answer 1

Step 1:

Rotation by 180° about the origin:

The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .

Then,

P(-3,4), Q(-1,4), R(-2, 1), S(-4, 1)

180° about vertex R

The rule for a rotation by 180° about R is ( 2, -1 )

CONCLUSION:

The rule for a rotation by 180° about R is ( 2, -1 )
