Question

Use graph paper for this question.

Plot points A(-2, 4); B(2, 1) & C(-6, 1)

The line of symmetry of ∆ ABC & the line BC are both lines of symmetry of a quadrilateral ABCD.

a) Write the geometric name of the figure ABCD.

b) Write down the equations of the lines of symmetry of the quadrilateral ABCD.

• A. Rectangle, y = 2, = -1
• B. Rhombus, y = 1, = -2
• C. Arrow head, y = 2, = 2
• D. Rhombus, y = -1, = 2
• E. Rectangle, y = 2, = -1
• F. Parallelogram, y = 1, x = -2
• G. Parallelogram, y =x, y = 1

Answer 1

The correct option is B

Rhombus, y = 1, = -2

ABCD is a Rhombus.

Lines of symmetry are

L₁: y = 1 & L₂: = -2
