Quadrilateral Basics
What is a quadrilateral?
(A shape with 4 sides)
What shape has 2 pairs of parallel sides and no right angles?
(Parallelogram)
What is a line of symmetry?
(A line that divides a shape into two identical parts.)
What is rotational symmetry?
(When a shape looks the same after being turned less than a full circle.)
I have 4 right angles and 2 pairs of equal sides, but my sides are not all the same. What am I?
(Rectangle)
True or False: A square is always a rectangle.
Which quadrilateral has 4 equal sides but does not always have right angles?
(Rhombus)
How many lines of symmetry does a rectangle have?
(2 lines)
True or False: A square has rotational symmetry.
(True)
I have 4 equal sides and no right angles. What am I?
(Rhombus)
How many sides does a trapezium have?
(4 sides)
Which shape has opposite sides that are equal and 4 right angles?
(Rectangle)
True or False: A parallelogram always has at least one line of symmetry.
(False)
What is the order of rotational symmetry for a rectangle?
(Order 2)
I have only one pair of parallel sides. What am I?
Trapezoid
Name a quadrilateral with only one pair of parallel sides.
(Trapezium)
True or False: All rhombuses are squares.
How many lines of symmetry does a square have?
(4 lines)
What is the order of rotational symmetry for a square?
(Order 4)
I have 4 equal sides, 4 right angles, and 4 lines of symmetry. What am I?
Square
What do we call a quadrilateral where all sides are equal, and the angles are 90 degrees?
(Square)
What is the difference between a rectangle and a parallelogram?
(A rectangle has 4 right angles; a parallelogram does not need to.)
Name a quadrilateral that has no lines of symmetry.
(Trapezoid, unless it is isosceles)
Does an isosceles trapezoid have rotational symmetry? Why or why not?
(No, because it does not look the same after any rotation.)
I have no parallel sides and no lines of symmetry. What am I?
(Irregular quadrilateral)
