A quadrilateral with 2 pairs of equal sides could be a parallelogram,
a trapezoid, a kite, or a rectangle.
If all 4 sides are equal, then it could also be a rhombus or a square.
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Its opposite angles are also equal in measure. The shape of a parallelogram can vary, but it always has pairs of parallel sides. It can look like a rectangle, a rhombus, or a square, depending on the specific characteristics of its angles and sides.
Not sure about sids, but it has 7 sides.
9 sides
An octagon has 8 sides
A pentagon has 5 sides
Scalene.
A pentagon has 5 sides
Isosceles
It is a nonagon which is a polygon with 9 sides
A 20p coin has a total of 6 sides: one for each of the two faces (obverse and reverse) and the four edges. The term "SIDS" typically refers to "sides," so in this context, a 20p coin can be said to have 6 sides.
Assuming that sids is your way of spelling side and sides, it would appear that you are describing an obtuse angled isosceles triangle.
A shape with 12 sides and 12 angles is known as a dodecagon. In geometry, a dodecagon can be regular, meaning all sides and angles are equal, or irregular, where the sides and angles can vary. Regular dodecagons have internal angles measuring 150 degrees each.
