Date _____________
Standard:
46.G.1 draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines and identify these in
two-dimensional figures
47.G.2 classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence
of angles of a specified size. Recognize right triangles as a category, and identify right triangles
49.G.3 recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the
line into matching parts. Identify line-symmetric figures and draw lines of symmetry
1. Write >, <, or =.
Acute angle ______ 90°

accept all correct responses
8. d. fish
9. H
b. R E
D one line of symmetry on the H is acceptable
10. a. horizontally
b. no, you can only fold it one way to make both sides match
11. acute, isosceles; accept all accurate drawings
12. examples may include but are not limited to:
both have four sides/are quadrilaterals
both are polygons (closed figures, straight sides, plane figures)
both have at least one pair of parallel sides
a square has 2 pair of parallel sides; a trapezoid can have only 1 pair of parallel sides
a square has four right angles; a trapezoid can have no more than 2 right angles
a square has 2 lines of symmetry; a trapezoid has either zero or 1 line of symmetry
squares have 4 congruent sides; a trapezoid can have only 2 congruent sides
13.a. Arroyo Dr., Malinda Rd., Spivey Rd., James Ave., or Raymond Ave. (names 1)
b. Raymond Ave., Spivey Rd., Malinda Rd., Arroyo Dr., or Vincente (names 2)
c. perpendicular
