  • True of False: A parallelogram is also a trapezoid.
    True, because a parallelogram technically has at least one pair of parallel sides like a trapezoid.
  • What is true of any polygon?
    It is a closed shape with at least 3 straight sides and 3 angles.
  • Which could be the sides of a parallelogram?
    It is B because a parallelogram has 2 pairs of opposite, equal sides.
  • Chase said he can draw an equilateral obtuse triangle. Is he correct?
    Chase is not correct because equilateral triangles have only acute angles.
  • True or False: All  3 sides of an isosceles triangle are congruent.
    False: Only 2 sides are congruent and the third side is different.
  • Which statement is NOT true?
    A,  because a trapezoid is NEVER a rectangle because it doesn't have 2 pairs of parallel sides.
  • Classify this triangle by its sides and angles.
    Scalene, Right (See the square corner?)
  • All triangles have at least _____ acute angles.
    2
  • What are the properties of a quadrilateral?
    A quadrilateral has 4 sides and 4 angles.
  • True or False: A trapezoid is also a parallelogram.
    False: A trapezoid only has 1 pair of parallel sides and a parallelogram has 2 pairs.
  • What are the properties of a square? I'm looking for the most specific properties.
    A square is a parallelogram with 4 congruent (equal) sides and 4 right angles.
  • Why is a square ALSO a rectangle?
    A square has 2 pairs of parallel sides and 4 right angles...just like a rectangle.
  • Using a protractor, Jacob drew a triangle with all equal angles. What type of triangle did he draw? Use 2 names.
    an equilateral, acute triangle
  • Name 4 polygons that  have 2 pairs of opposite parallel sides.
    parallelogram, rectangle, rhombus, square
  • Which of the following statements is NOT true?
    It is C because a trapezoid has 1 pair of parallel sides.
  • Quinn says that the figure is a rhombus, but Brooke disagrees. Who is correct and why?
    Brooke is correct because the figure is a parallelogram. A rhombus ALWAYS has congruent (equal) sides and a parallelogram had 2 pairs of opposite equal sides.
  • Look at the quadrilaterals. Name the shapes that can only be classified as quadrilaterals AND trapezoids
    O, R, and S
  • Triangles can be classified by the length of their ________ and the measure of their ________.
    sides, angles
  • What are the properties of a trapezoid?
    A trapezoid is a special quadrilateral with at least one pair of parallel sides.
  • A rectangle has one side that is 6 centimeters long and another side that is 4 centimeters long. What is the perimeter of the rectangle?
    20 centimeters
  • What quadrilateral is both a rectangle AND a rhombus?
    square
  • Classify this polygon in the most SPECIFIC way.
    trapezoid
  • Which describes BOTH triangles?
    It is D because ALL triangles have at least 2 acute angles. It's the third angle that classifies or names it.
  • Which color flags show only parallelograms?
    red, blue, and orange
  • Classify this triangle by its sides and angles.
    Isosceles, obtuse
  • True or False: A rectangle can be classified as a rhombus.
    False, because a rectangle does not have congruent (equal) sides.
  • Classify this triangle by its sides and angles.
    Equilateral, Acute
  • If you cut a square into 2 identical triangles, what type of triangles will you make? Use 2 names.
    isosceles, right
  • Which 2-D figure can be classified using every name on the Venn diagram?
    square
  • Why is a rectangle NEVER a square?
    A rectangle does NOT have congruent (equal) sides.
  • Classify this polygon in the most SPECIFIC way.
    rhombus
  • This question has 2 parts. Part 1 - What is a regular polygon? Part 2 - Name an example..
    A regular polygon has congruent (equal) sides AND congruent (equal) angles.Examples: square, equilateral triangle
  • What is the greatest number of right angles any triangle can have?
    only 1
  • Classify this triangle by its sides and angles.
    Isosceles, Right
  • True or False: Rhombuses are always parallelograms.
    True, because rhombuses have 2 pairs of parallel sides.
  • Parker says that this shape is a parallelogram. Is he correct? Why or why not.
    Parker is not correct because the "kite" does NOT have 2 pairs of opposite parallel sides.
  • True or False: Every trapezoid is a quadrilateral.
    True
