Lines, Angles, and Symmetry Homework

4.G.1

“Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.”

Questions 1 to 5: the line, ray and segment identifications, the three line-pair classifications and the three angle types.

4.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.”

Questions 6 and 7, classifying the right triangle and stating the rectangle's parallel pairs and right angles.

4.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.”

Question 8's three symmetry counts and the letter H judgment in question 9.
