What is a nonconvex polygon?
A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
Why is parallelogram named parallelogram?
because both lines are paralle so it is a parallelogram
When is a square a parallelogram?

Is concave a parallelogram?

Is a rhombus a concave?
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
Is a rhombus concave or convex?
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
What shape you will always get when you combine a triangle pattern block and a rhombus pattern block?

What quadrangle has two pairs of equal side but is not a parallelogram?
A kite or, if concave, an arrowhead or chevron.
What is the name of the figure that results when a parrallelogram is removed from a similar but larger parallelogram with which it shares a corner?
The remaining shape could be a [concave] hexagon although in some circumstances it could be a smaller parallelogram.
What other than a square is a four sided shape?
Rectangle, rhombus, parallelogram, trapezium, kite. Also a chevron, which is a concave 4-sided shape.
What do a trapezoid and a triangle make?
It depends entirely on their relative shapes and sizes. They could make a triangle, a parallelogram, a square, or a pentagon or even a concave heptagon.
What shape does a triangle and a parallelogram makes?
Assuming they don't overlap, these are some of the possible shapes: a concave pentagon, a trapezium, a concave seven or eight sided figure (neither of the last two is a polygon but two polygons touching one another).
Is a parallelogram a parallelogram?
yes a parallelogram is a parallelogram
Which quadrilaterals have two obtuse angles?
Every parallelogram and most trapezoids have.Oh wait! It seems to me that every quadrilateral, regular or irregular, that'snot a rectangle and not concave, must have at least two obtuse angles.
What is the types of special quadrilaterals that will appear when you join two congruent equilateral triangles?
Depending on how they are joined, you can get a square, rectangle, rhombus, parallelogram, kite, arrowhead (or delta). You could also get a concave pentagon or hexagon.
