Question

The point P(5,3) was rerflected in the origin to get the image P'.

a. write the coordinates of P'.

b.If M is the foot of the perpendicular from P to the x-axis , find the coordinates of N

c.If N is the foot of the perpendicular from P' to the x-axis , find the coordinates of N

d. Name the figure PMP'N

e. Find the area of the figure PMP'N .

Answer 1

​a. P'(-5,-3)

b. M(5,0)

c. N(-5,0)

d. Parallelogram

e. Base is 3 (length of MP and NP') and height is MN=10, so area=3*10=30.
