Question

The points(–3, –3) (–1,–1 ), (1, 1) and (3, 3) connected in the order from a _________________

• A. Square
• B. Rectangle
• C. Rhombus
• D. Triangle

Answer 1

The correct option is D

Triangle

Let A, B, C, and D represent (–3, –3) (–1,–1 ), (1, 1) and (3, 3) respectively.

Length of $AB=BC=CD=\sqrt{2^2+2^2}=2\sqrt{2}$

Length of $AD=\sqrt{(3+3{)}^2+(3+3{)}^2}=6\sqrt{2}$

AD = AB + BC + CD

Therefore points A, B, C, and D are on a straight line; y = x. So, the points form a line segment.
