what is a regular quadrilateral

Regular polygon. Regular Quadrilaterals Of the long list, only a square is a regular quadrilateral. So all other quadrilaterals are irregular. Square. Square (regular quadrilateral): all four sides are of equal length (equilateral), and all four angles are right angles. So I thought a regular polygon would mean a shape with regular angles.

Event B is completely independent to that of event B The sum of all the angles of a quadrilateral is 360 degrees. We know it is true for triangles, although you might not be able to prove it, or even justify it, beyond the fact that your Year Five teacher told you it was true during a particularly soul-crushing numeracy hour. The sum of all the interior angles of a quadrilateral is 360 degrees so each angle of a regular quadrilateral must be 90 degrees. …, of AONE.Name the side opposite 20 in AONE.5) Give the vertices of APNC.6) Name the angles of APNC.​, TO THOSE WHO ANSWER MY QUETIONS CORRECTLY THANK YOU SO MUCH I OWE MY COUSINS GRADES TO ALL OF YOU GUYS HOPE TO BLESS YOU ALL AND LOVE YOU GUYS STAY SA A square, the regular quadrilateral, is a quadrilateral with 4 equal sides and 4 equal angles: If a quadrilateral has two pairs of equal sides and 4 equal angles, it is a rectangle: If a quadrilateral has 2 pairs of equal sides and parallel sides it is a parallelogram: Some examples of the quadrilaterals are square, rectangle, rhombus, trapezium, and parallelogram. Some examples are rectangle, rhombus, trapezium, kite, and parallelogram. Find four straight objects to use as line segments (four = quadr; side = lateral).
