How many sides does a quadrilateral have? — 4.Quadri means "four" — a quadrilateral always has exactly 4 sides.
Which shape has 4 equal sides AND 4 right angles? — Square.A square has all 4 sides equal AND all 4 angles are 90° (right angles).
A right angle measures exactly: — 90°.A right angle is exactly 90°. It looks like the corner of a square or a piece of paper.
Which quadrilateral has exactly ONE pair of parallel sides? — Trapezoid.A trapezoid has exactly one pair of parallel sides. Parallelograms, rectangles, and rhombuses all have two pairs.
Is a square a type of rectangle? — Yes, because it has 4 right angles and opposite sides equal.A rectangle needs 4 right angles and opposite sides equal. A square satisfies both — so every square IS a rectangle!
Which shape has opposite sides that are equal and parallel, and 4 right angles, but sides are NOT all equal? — Rectangle.A rectangle has 4 right angles and opposite sides equal and parallel — but the two different side lengths don't have to be equal to each other.
How many pairs of parallel sides does a parallelogram have? — 2.A parallelogram has 2 pairs of parallel sides — that's how it gets its name.
What does it mean to "partition" a shape? — To divide it into equal parts.To partition a shape means to divide it into equal parts, each with the same area.
A circle is cut into 4 equal parts. What fraction is each part? — 1/4.4 equal parts → each part is 1/4 of the whole circle.
A square is divided into 2 equal parts. What is each part called? — A half.2 equal parts → each part is 1/2 (one half) of the whole.
You partition a rectangle into 8 equal parts and shade 3 of them. What fraction is shaded? — 3/8.3 shaded out of 8 total equal parts = 3/8.
All parts of a partition must be: — The same area.In a valid partition, all parts must have equal AREA. They can have different shapes (like different-shaped pieces of the same size).
A pizza is cut into 6 equal slices. You eat 2 slices. How much of the pizza is left? — 4/6.6 − 2 = 4 slices remain. 4 out of 6 = 4/6 of the pizza is left.
A square is split into 4 equal parts. If you shade 1 part, what fraction is UNshaded? — 3/4.4 total parts − 1 shaded = 3 unshaded parts. 3 out of 4 = 3/4 is unshaded.
If a shape is divided into 3 equal parts, what fraction does each part represent? — 1/3.3 equal parts means each part = 1/3 of the whole.
What is a unit square? — A square with sides of length 1 unit.A unit square has sides each exactly 1 unit long, so its area = 1 × 1 = 1 square unit.
You count 12 unit squares inside a rectangle. What is its area? — 12 square units.Counting 12 unit squares means the area = 12 square units. The unit depends on what size unit you're using.
A rectangle is 4 units long and 3 units wide. How many unit squares fill it? — 12.4 columns × 3 rows = 12 unit squares. Area = l × w = 4 × 3 = 12 sq units.
Area is measured in: — Square units.Area is always measured in square units (like square cm, square inches, square feet).
A square has sides of 5 units. What is its area? — 25 sq units.Area of a square = side × side = 5 × 5 = 25 square units.
When filling a shape with unit squares, what TWO rules must you follow? — No gaps, no overlaps.Unit squares must cover the shape with no gaps (empty spaces) and no overlaps (stacking).
A rectangle has 5 rows of unit squares, with 6 squares in each row. What is the area? — 30 sq units.5 rows × 6 per row = 30 unit squares. Area = 30 square units.
