How many diagonals a convex quadrilateral have?
A quadrilateral has 2 diagonals. It does not matter whether it is convex or not.
How can you tell whether a quadrilateral is convex or not convex?
If any of the angles is greater than 180 degrees, the quadrilateral is concave.
What is the length of a rectangle of 2cm going down and 5cm going across?
I am not sure what the point is for you to give us the dimensions of a rectangle and then ask what one of those dimensions is. Perhaps you are not sure whether the shorter or the longer of the two dimensions would be considered the length, and which the width. I would say that a rectangle measuring 2cm x 5cm is 2cm wide and 5cm long.
Is a concave quadrilateral less than 180 degrees?
The sum of the interior angles of a quadrilateral is 360 degrees (not 180). The sum of the exterior angles is also 360 degrees. Whether the quadrilateral is convex or concave is not relevant.
Does a quadrilateral have 4 straight lines?
No.A quadrilateral is any four sided figure.So it doesn't matter whether one of the sides is curved or straight as long as it is four sided.
