4 quad-four, and lateral-side
How many sides must a quadrilateral have?
100
A regular quadrilateral has the same length of sides and degrees of angles. Eg. square (regular), rectangle, rhombus and trapezoid (irregular).
What is the difference between irregular and regular quadrilaterals? Give some examples of both (Two irregular for double points).
100
1, the shape that has this is a kite or a trapezoid.
What is the smallest number of lines of symmetry a quadrilateral can have?
100
A complex quad or "self-intersecting" quad is a quadrilateral that has one or more pair of intersecting lines.
What is a complex quad, and what are its properties?
100
No, some other names for quadrilaterals are: Quadrangle (four angles) or Tetragonal (Four and Polygon).
Are quadrilaterals always called quadrilaterals?
200
360 degrees!! A quadrilateral must have 4 sides each adding up to 360 degrees.
How many degrees do the interior angles of a quadrilateral add up to?
200
A square is a rectangle, but a rectangle is not a square.
What is the relationship between a rectangle and a square?
200
4, the only shape that has these many is the square.
What is the greatest number of lines of symmetry a quad can have?
200
No, a polygon can not have intersecting lines.
Are "self-intersecting" quadrilaterals still polygons?
300
179 degrees, because if one angle reaches 180, it would b a triangle.
What is the maximum number of degrees one angle of a quadrilateral can have?
300
A rhombus has all equal sides (based on length), but not necessarily all equal angles. And a kite has different sizes of sides and different angles.
How is a kite different from a rhombus?
300
1,0
What is the number of lines of symmetry of a trapezium?
300
Yes, it can. However it does not need to have one.
Can a complex quadrilateral still have a line of symmetry?
400
90 degrees, a regular quadrilateral is a fancy way of saying a square.
An regular quadrilateral shape must have how many degrees in one of its interior angles?
400
A trapezium has no equal sides, no parallel lines and no equal angles. A trapezoid has one set of parallel lines, but angles and lengths of sides.
What is the difference between a trapezoid and a trapezium?
400
No
Do all quads have lines of symmetry?
400
Yes, even though they are "complex" they are still quadrilaterals and thus they have to have 360 degrees.
Does a complex quadrilaterals angles still add up to 360 degrees?
500
All of them.
Which quadrilateral shape can have the most total degrees?
500
A quad does not have to have two sets of parallel lines, while a parallelogram does.
What is the difference between a parallelogram and a quadrilateral?
500
It is a line that divides a shape in half
What is a line of symmety
500
No, because they have intersecting lines.
Are complex quadrilaterals polygons?
