What is a line of symmetry?
(A line that divides a shape into two identical parts.)
100
What is rotational symmetry?
(When a shape looks the same after being turned less than a full circle.)
100
What shape has 2 pairs of parallel sides and no right angles?
(Parallelogram)

What are the three 2D views we look at when drawing a 3D object?
(Top, Front, Side)
200
How many lines of symmetry does a rectangle have?
(2 lines)
200
True or False: A rhombus has rotational symmetry.
(True)
200
Which quadrilateral has 4 equal sides but does not have any right angles?
(Rhombus)
200
Why is it important to look at all three views when constructing 3D shapes?
(You need to look at all 3 views to know how to construct your object)
300
True or False: A parallelogram always has at least one line of symmetry.
(False)
300
What is the order of rotational symmetry for a rectangle?
(Order 2)
300
Which shape has opposite sides that are equal and 4 right angles?
(Rectangle)
300
What two views tell us about an objects height?
(Front & Side)
400
How many lines of symmetry does a square have?
(4 lines)
400
What is the order of rotational symmetry for a square?
(Order 4)
400
True or Flase: If a rhombus has the mimum properties of 2 pairs of parallel lines, and 4 equal sides, then a square can be considered a rhombus

500
Name a quadrilateral that has no lines of symmetry.
(Right Angle Trapezoid)
500
Does an isosceles trapezoid have rotational symmetry? Why or why not?
(No, because it does not look the same after any rotation.)
500
What is the difference between a rectangle and a parallelogram?
(A rectangle has 4 right angles; a parallelogram does not need to.)
