Question

Determine the most precise name for the quadrilateral with vertices at A(–7, –2), B(0, 2), C(4, –5), and D(–3, –9).

Answer 1

All angles are 90 degrees, which cancels out a kite and a rhombus, leaving you with two options (rectangle or square). Using Pythagoras' theorem, you can work out that all sides are also of equal length, which means this shape is a square :)
