Any four-sided, 2-dimensional shape with straight sides is called a <u>quadrilateral</u>.
There are 6 special types of quadrilaterals:
<u>Rectangle</u>
- Opposite sides are parallel and equal in length
- All interior angles are 90°
<u>Square</u>
- All sides are equal in length
- All interior angles are 90°
<u>Rhombus</u>
- All sides are equal in length
- Opposite sides are parallel
- Opposite angles are equal
<u>Parallelogram</u>
- Opposite sides parallel and equal in length
- Opposite angles are equal
<u>Trapezoid</u>
- One pair of opposite parallel sides
<u>Isosceles Trapezoid</u>
- One pair of opposite parallel sides
- One pair of non-parallel sides equal in length
- Two pairs of equal base angles
<u>Kite</u>
- Two pairs of adjacent sides equal in length
- The angles included between the sides of differing lengths are equal
<u>Conclusion</u>
A four-sided shape that has four congruent angles and sides is a SQUARE.
