2. How many right angles does a rectangle have?
A) 2
B) 3
C) 4
D) 1
A square has 4 lines of symmetry: 2 diagonal and 2 through the midpoints of opposite sides.
3. Which quadrilateral has exactly one pair of parallel sides?
A) Parallelogram
B) Rectangle
C) Rhombus
D) Trapezoid
A trapezoid is defined as a quadrilateral with exactly one pair of parallel sides.
4. How many lines of symmetry does a regular hexagon have?
A) 4
B) 5
C) 6
D) 8
A regular hexagon has 6 lines of symmetry, one through each pair of opposite vertices and one through each pair of opposite sides.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A square is a special type of rectangle because it has 4 right angles.
A square meets all the criteria of a rectangle (4 right angles, opposite sides equal) and adds the requirement that all sides are equal.
2. A rhombus has 4 equal sides but its angles are not always right.
A rhombus has 4 equal sides, but unlike a square, its angles can be any measure as long as opposite angles are equal.
3. A regular octagon has 8 lines of symmetry.
A regular octagon has 8 lines of symmetry, one for each side and one for each pair of opposite vertices.
4. Opposite angles in a parallelogram are always equal.
In a parallelogram, opposite angles are congruent (equal in measure).
5. A shape with all sides equal and all angles equal is called a regular polygon.
A regular polygon has all sides the same length and all angles the same measure.
