What else can I help you with?
Do all polygons have diagonals?
no
What polygons always have congruent diagonals?
Regular polygons. A square and rectangle will have congruent (equal length) diagonals.
Who diagonals bisect opposite angles?
The principal diagonals of all regular polygons.
Which of these polygons has congruent diagonals but not perpendicular?
It is not possible to answer the question since there are no polygons "following".
Which figure have congruent diagonals?
All regular polygons.
What polygons have congruent diagonals but not perpendicular?
square and rectangle
Which of the following polygons always has congrunt diagonals?
rectangle
How many diagonals does a polygon with 32 sides have?
It has 464 diagonals. I used n(n-3)/2. Works for all polygons.
What figures have parallel diagonals?
Regular polygons with even sides if there are 6 or more of them; selected irregular polygons with seven or more odd numbers of sides.
What polygons are all the diagonals always longer than the sides?
squares,rectangles,regular pentagons
Why you need to minus 3 from n in finding the diagonals in the polygons?
You cannot draw a diagonal from a vertex to itself. So that is 1. Also, the diagonals to the adjacent vertices on either side will actually be the sides of the polygon, not diagonals. Those are the other 2.
What has congruent diagonals that is not a rectangle?
Any regular polygon. Lots of irregular polygons can also have congruent diagonals, for example a kite. The answer should not be "a square" because it is a rectangle - a special case but a rectangle nevertheless.
