Yes, be it a common convex quadrilateral or a concave quadrilateral.
For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length.
It is similar for a concave quadrilateral.
A quadrilateral with all right angles is a rectangle.
It is an irregular quadrilateral if the 2 long sides are adjacent, and a parallelogram if the two long sides are not adjacent, because having two sets of opposite sides of equal length must form parallels. Only if all of the angles are right angles would it be a rectangle.
Opposite angles are angles across from each other in intersecting lines. For example, see the figure below:a-> X
60o Angles in a triangle sum to 180o With 3 angles all the same each one is 180o ÷ 3 = 60o
no its false
It can, but usually doesn't.
It is possible, but parallelograms do not. Some quadrilaterals do.
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
a quadrilateral is any shape with 4 sides, the sides could be any length a rectangle, square and any other figure with four sideds is a quadrilateral
A rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.
Each of the four interior angles of a square (i.e. a regular quadrilateral) measures 90 degrees
Measure each of the 4 angles with a protractor and they should total 360 degrees.
That will depend on what type of 4 sided quadrilateral it is but its 4 interior angles add up to 360 degrees.
No because the 4 interior angles of a quadrilateral add up to 360 degrees
Yes it can. All you need to form a quadrilateral is four sides. The angles can be any size as long as the add up to 360 degrees.
