Question

A plot of land is triangular in shape as shown below. The shaded section inside the triangle shows the shape of a farm on the plot.



Jose said that the shape of the farm is not a rectangle with angles equal to 90°. Jose is correct. How did he arrive at this conclusion? Using complete sentences, justify your answer.

Answer 1

There are only 3 sides. The angles add up to 180 degrees. For a rectangle, the angles add up to 360 degrees. Finally, there is only one right angle... not 4. I dunno if your instructor wants more than this?
