What are at least facts and features of a quadrilateral with equal sides and 4 interior angles of 90 degrees but it is not a square?

Answer 1

1 It's a rhombus whose diagonals form 4 right anges

2 It looks like a skewed over square

3 It's in the class of polygons called quadrilaterals because it has 4 sides

4 It has 4 equal sides and is known as a rhombus

5 It has 2 equal obtuse and 2 equal acute interior angles

6 Its interior angles add up to 360 degrees

7 Its 4 exterior angles add up to 360 degrees

8 It has 2 unequal diagonals that intercept each other at 90 degrees

9 It has a perimeter which is the sum of its 4 sides

10 It has an area which is its base times its perpendicular height

11 Its area can also be calculated as half the product of its diagonals

12 It can tessellate

13 It has 2 lines of symmetry

14 It has rotational symmetry to the order of 2

15 It can be divided into 2 congruent isosceles triangles

16 It can be divided into 4 right angle triangles

17 It can be used in conjuction with trigonometry

18 Its properties can be found using Pythagoras' theorem

19 It can be congruent or similar to other rhombuses

20 It can rotate and has infinite images within a circle

21 Its name comes from the Greek word rhombos meaning a parallelogram with oblique angles and equal sides
