Can it be this?
True or False
100

All sides and angles are equal.

Square

100

Square, Rectangle, Irregular Quadrilateral

Hint: look at the angles

Irregular Quadrilateral (the angles are not equal in any way)

100

Name 3 characteristics of a square

all sides are equal, all angles are equal, and opposite sides are parallel (you could also say that adjacent sides are perpendicular). each angle is 90°.

100

A quadrilateral exists with all sides equal. Must this quadrilateral be a square, or can it be any other shape? If so, which shapes can it be other than a square?

The quadrilateral can also be a rhombus.

100

A quadrilateral has four sides.

True

200

Has only one pair of parallel sides.

Trapezoid/Trapezium

200

Isosceles Trapezoid, Isosceles Triangle, Rhombus

Hint: look at the type

Isosceles Triangle (it isn't a quadrilateral) or Rhombus (it isn't isosceles)

200

What are the 3 properties present in all quadrilaterals?

They have four sides. They also have four angles. The sum of the measure of all of the angles is 360°.

200

A parallelogram has one side of 7 centimeters, AB. Can you be certain of any other side length of the parallelogram?

The side parallel to side AB will also be 7 centimeters.

200

The sum of all angles in a quadrilateral is 300°.

False, the sum of all angles in a quadrilateral is 360°

300

Has no unique properties. (meaning: nothing is special about the quadrilateral)

Irregular Quadrilateral

300

Dart, Trapezoid (not isosceles), Paralellogram

Look at the type of shape

Dart (since it is a concave quadrilateral)

300

Define an isosceles trapezoid, giving 3 characteristics about it.

A trapezoid is a quadrilateral with one pair of parallel sides and two equal sides.

Has one pair of parallel sides, two equal sides, and equal base angles. Opposite angles are supplementary, and diagonals are equal. (have to say any three of these)

300

How can you find out whether a trapezoid is isosceles or not?

If two sides are equal, and the diagonals and base angles are equal, then the trapezoid is isosceles.

300

The name of any quadrilateral with opposite angles equal is 'trapezoid'

False, the name of any quadrilateral with opposite angles equal is 'parallelogram'

400

What was the shape of the highlighter tip (from the slideshow)?

Isosceles Trapezoid

400

Kite, Rhombus, Square

Look at the sides

Kite (not all sides are equal)

400

What is a parallelogram? List the types of parallelograms.

A parallelogram is a quadrilateral with opposite sides equal and parallel. The opposite angles are equal and adjacent angles are supplementary.

The types of parallelograms include the following: rectangles, squares, and rhombuses.

400

A square is always a rectangle. Is a rectangle always a square? If not, give an example where a rectangle is not a square.

If one side of the rectangle is one length, say x, while the side adjacent to it is length y, and x is not equal to y, then the rectangle is not a square. (does not have to be said exactly like this for the points to count)

400

Squares are rectangles, rhombuses, parallelograms, and quadrilaterals.

True

500

Has a reflex interior angle.

If you get this right, you get double points!

Dart (Concave Quadrilateral)

500

Differentiate between an isosceles trapezoid and a rhombus (3 points)

Rhombus has all sides equal, opposite angles equal, and opposite sides parallel.

Isosceles trapezoid had only two sides equal, base angles equal, and only two sides parallel.

500

Bet any amount of points less than the absolute value of the amount of points you have, because this is a DAILY DOUBLE!!!

The question is: Classify the quadrilaterals, discluding dart, kite, irregular quadrilateral, and complex quadrilateral.

If you don't understand, remember the Venn diagram!

There are two types of quadrilaterals; trapezoids and parallelograms. Rectangles and rhombuses are the subdivisions of parallelograms and squares fall between rectangles and rhombuses.

500

The angles of a shape are 25°, 135°, 65°, and 115°. Can this shape be a quadrilateral?

No, the angles add up to 340°.

500

Concave quadrilaterals include trapezoids and parallelograms while convex quadrilaterals include darts.

If you get this right, 1250! If you get this wrong, -250.

False, convex quadrilaterals include trapezoids and parallelograms while concave quadrilaterals include darts.
