I am any shape with 4 sides. What am I called?
Quadrilateral
Square
4 congruent sides, 4 vertices, 4 right angles
How are all quadrilaterals the same?
They all have 4 sides
How are squares and rhombuses different?
Squares always have right angles, rhombuses can have acute and obtuse angles
What is the area of each half of the geoboard?
8 square units
I am a shape with at least 3 sides. What am I called?
Polygon
Polygon
3 or more sides
How are squares and rhombuses the same?
They both have 4 congruent sides, and they sometimes have 4 right angles
How are parallelograms and trapezoids different?
What is the area of each fourth of the geoboard?
4 square units
I am a 4 sided shape that has 4 congruent sides, and can sometimes have obtuse and acute angles, or right angles. What shape am I?
Rhombus
Trapezoid
4 sides, 4 vertices, one pair of parallel lines, diagonal sides
How are parallelograms and rectangles the same?
They both have 4 sides, and they both have 2 sets of congruent sides, and 2 sets of parallel sides
How are rectangles and squares different?
Squares have 4 equal sides, rectangles have 2 sets of equal sides
Is the geoboard divided into exactly half? How do you know?
Yes - even though the sides are not symmetrical, each half has 8 square units
