Triangle
Honeybees use millions of me to store their honey perfectly. Six sides and six angles. What am I?
Hexagon
What do we call the corners of a shape?
Vertices
If a square has sides of 3 units, what's the perimeter?
12 units
Trapezoid
At least 1 pair of parallel sides
All four of my sides are equal, and all four of my angles are perfect 90° angles. I'm found everywhere from windows to tiles. What am I?
Square
I have four right angles like my square cousin, but each two of my opposite sides are equal. You see me in doors and paintings. What am I?
Rectangle
A quadrilateral has how many sides, vertices, and angles?
4 vertices
4 sides

12 units
Rectangle
- 4 Right angles
- 2 pairs of opposite equal sides
- 2 pairs of parallel sides
All four of my sides are equal length, but my angles are not 90°. I look like a tilted square, and a diamond is my fancy cousin. What am I?
Rhombus
I'm six-sided and found naturally in snowflakes and rock formations. I pack together perfectly with no gaps or overlaps. What am I?
Hexagon
Which shapes has the largest number of sides trapezoid, square, rectangle, or rhombus?
None of them. All of them are quadrilaterals and have 4 sides.
We're walking around a hexagon that has 5-foot sides. How far do we walk?
30 units
Square
- 4 Right angles
- 4 equal sides
- 2 pairs of parallel sides
I have four sides and four angles, but only ONE pair of parallel sides. I'm often used in roofs and as a weight on a seesaw. What am I?
Trapezoid
I have exactly one more side than a quadrilateral but one fewer than a hexagon. What am I?
Pentagon
Name all the shapes with only right angles.
Square
Rectangles
Which covers more space:
a 4×4 square or
a 5×3 rectangle?
The square is 16 unit2 and the rectangle 15 unit2, so it is the square.
Rhombus
- 4 equal sides
- 2 pairs of parallel sides
I'm the symbol of a famous military building in Washington D.C. I have five sides and five angles. What am I?
Pentagon
You'll see me painted on streets as a stop sign. I have eight sides and eight angles. What am I?
Octagon
What do rectangles and squares have in common?
4 sides, 4 right angles, opposite sides equal
Sarah's garden is a rectangle 10 feet long and 5 feet wide. What is the perimeter and the area?
Perimeter: 2 x (10 + 5) = 30 ft.
Area: 10 x 5 = 50 ft2
