Question

Use graph paper for this question.

Plot the points A(-2, 0), B(4, 0), C(1, 4) & D(-2, 4).

Draw the line of symmetry of ∆ABC, name it L₁.

Point D is reflected about L₁ to get image E.

a) Write coordinates of E

b) Write equations of the lines of symmetry of figure ABED

• A. E(2 , 4) = 2, y = 1
• B. E(4 , 4) = 1, y = 1
• C. E(2 , -4) = -2, y = 2
• D. E(2 , 4) = 0, y = 2
• E. E(4 , 4) = 1, y = 2
• F. E(-2 , 4) = -1, y = 2
• G. E(4 , 4) = 0, y = 2

Answer 1

The correct option is E

E(4 , 4)

= 1, y = 2

L₁ is = 1.

E(4, 4)

ABED is a rectangle.

Lines of symmetry are = 1, y = 2
