Rectangle
All interior angles are right angles
Diagonals bisect each other, diagonals are congruent
- ∠3 = 33°
- ∠1 = ∠5 = 90° - 33° = 57°
- ∠2 = 180° - 2*57° = 66°
- ∠4 = 180° - 66° = 114°
(12)
Rhombus
Diagonals are perpendicular and angle bisectors
- ∠2 = ∠5 = 53°
- ∠1 = ∠4 = 90° - 53° = 37°
- ∠3 = 90°
