Read each question carefully and follow the instructions to reflect points and shapes on the coordinate plane.
1. Plot the point A(3, 4) on the coordinate plane below. Then, reflect point A across the x-axis and label the new point A'. What are the coordinates of A'?
A' = ( )
2. Plot the point B(-2, 5) on the coordinate plane below. Then, reflect point B across the y-axis and label the new point B'. What are the coordinates of B'?
B' = ( )
3. Plot the vertices of triangle PQR: P(1, 1), Q(4, 1), R(1, 6). Draw the triangle. Then, reflect triangle PQR across the x-axis and label the new vertices P'Q'R'. Draw the reflected triangle.
4. Write the coordinates of the reflected vertices from question 3:
P' = ( )
Q' = ( )
R' = ( )
5. If a point (x, y) is reflected across the x-axis, what are the coordinates of the reflected point?
(x, y)
(x, -y)
(-x, y)
(-x, -y)
6. If a point (x, y) is reflected across the y-axis, what are the coordinates of the reflected point?
(x, y)
(x, -y)
(-x, y)
(-x, -y)
