How many diagonals does a 103 sided polygon have?
It works out as having 5150 diagonals
What shapes are not parallelograms?
Shapes having less than 4 sides or more than 4 sides are not parallelograms
How many axes of symmetry does a paralllelogram have?
It depends on the type of parallelogram:The classic generic-looking parallelogram, having no right angles, and having adjacent sides of unequal length, has no lines of symmetry (only point symmetry about the point of intersection of the diagonals).Special types of parallelograms are as follows:A square has 4 lines of symmetry: horizontal, vertical, and one containing each diagonal.A non-square rhombus has two lines of symmetry: one containing each diagonal.A non-square rectangle has two lines of symmetry: horizontal and vertical.
How many diagonals does tetra-decagon have?
A tetra-decagon is a 14 sided polygon having 77 diagonals
How many side are there in a convex polygon having 27 diagonals?
9 sides because a nonagon has 27 diagonals
Is an adjacent angle a right angle?
No adjacent means having a common endpoint or border.
Are quadrilateral parallelograms?
Quadrilateral can certainly be parallelograms, but they can also be squares, rectangles, and other 4-sided shapes.All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms.
What arr parallelograms?
A quadrilateral having both pairs of opposite sides parallel to each other.
What is true of a rhombus that is not true of all parallelograms?
All sides of a rhombus are the same length. Of the other parallelograms, only the square has identical side lengths (it differs from a rhombus by having four right angles).
Is a paralleogram also a square?
A square is defined by having 90 degree measures on each of its four angles, with all four sides congruent.Aparallelogramcan be a square, but not all parallelograms are squares.However, ALL squares are parallelograms.

Which is a quadrilateral having diagonals equal and bisecting each other but do not intersect at 90 degrees?
A rectangle.
