Bring your full reasoning toolkit. Multiple choice asks which capital letter has exactly 2 lines of symmetry (think H), how many pairs of parallel sides a regular hexagon has, what shape has 5 lines of symmetry, and what angle sits across from a 50° angle when two lines intersect. Fill-in-the-blanks dig into vertical angles, a 12-sided regular polygon, and the congruent triangles formed by a rectangle's diagonal.
These items push past simple recognition into the relationships between angles, sides, and symmetry — exactly the reasoning Grade 5 classification work will demand.

Lines and Symmetry
Part A: Multiple Choice
Circle the best answer for each question.
1. Which capital letter has exactly 2 lines of symmetry?
A) A
B) H
C) T
D) E
2. How many pairs of parallel sides does a regular hexagon have?
A) 1
B) 2
C) 3
D) 6
3. A shape has exactly 5 lines of symmetry. What shape could it be?
A) Rectangle
B) Regular pentagon
C) Hexagon
D) Rhombus
4. Two lines intersect and form four angles. If one angle is 50°, what is the angle directly across from it?
A) 40°
B) 50°
C) 130°
D) 180°
Part B: Fill in the Blank
Write the correct answer on each line.
1. When two lines intersect, the opposite angles formed are called vertical angles.
2. A regular polygon with 12 sides has 12 lines of symmetry.
3. The diagonal of a rectangle divides it into two congruent triangles.
4. An equilateral triangle has all three sides equal in length.
5. A straight angle measures 180 degrees and looks like a straight line.
