A trapezoid has exactly 1 right angle: Always Never Sometimes None of the Above
Sometimes Show how you know.
What does congruent mean?
Equal; same
A triangle with three different sized angles is called?
A scalene triangle
Is this statement true? All trapezoids have one pair of parallel sides.
Yes - this is true.
Is a square a rectangle?
Yes, it is a special kind of rectangle with congruent sides.
What are perpendicular lines?
Lines that form 90 degree angles
A kite can be a parallelogram
No, a kite does not have 2 pairs of parallel lines.
Is it possible for a trapezoid to have two right angles? If so, draw an example
Yes
How is a rhombus a parallelogram?
A parallelogram has opposite sides congruent and 2 sets of parallel lines. A rhombus also has these attributes.
Name two attributes that a square has.
Four right angles Four equal length sides
A rectangle has 4 right angles and a rhombus never has right angles.
False, when a rhombus is a square it has right angles.
Which attribute belongs to every rhombus, but does not belong to every parallelogram? A) All four sides have different lengths B) All four sides are equal in length C) The opposite sides are equal in length
B All four sides are equal in length. Prove with a representation why a rhombus has this attribute, but not every parallelogram does.
How is a trapezoid different than a square?
A trapezoid has only one set of parallel sides; a square has 2
Which of these shapes have opposite sides that are parallel? A Parallelogram B Rhombus C Both a parallelogram and a rhombus D Neither a parallelogram nor a rhombus
C Both a parallelogram and a rhombus
Some parallelograms are rectangles, and some rectangles are squares.
True
Is this statement true, based on the hierarchy of properties of polygons? Since all rectangles have four sides, all quadrilaterals have four sides.
Yes, this is a true statement based on the hierarchy - look at your flow chart to prove why this is true.
T/F All kites are squares
False
Is the following statement true based on a hierarchy of properties of polygons? Since all rectangles have four sides and 2 sets of parallel lines, they are not quadrilaterals.
No
A quadrilateral with all four sides equal must be a square.
False
Which statement is True?
a.) All squares are kites
b.) All parallelograms are rectangles
c.) All quadrilaterals are paralleograms
