Classifying Triangles and Quadrilaterals Sort
Sort eight shapes: right vs not-right triangles, then quadrilaterals by parallel pairs and right angles. Explain why Shape D is also a parallelogram.
Lines, Rays, and Angles Labelling
Label eight figures from a word bank (line, ray, segment, three angle types, parallel, perpendicular), then name them all inside right trapezoid ABCD.
Lines, Angles, and Symmetry Homework
Picture-based geometry homework: name lines and rays, classify pairs and angles near 40°, 90° and 130°, count symmetry lines, and judge the letter H.
Lines of Symmetry
Fold-test symmetry: judge dashed lines on a heart, a diagonal-cut rectangle and the letter E, draw all lines on four shapes, and settle Leo's claim.
Lines and Angles Vocabulary Crossword
Printable 4th grade geometry crossword with a word bank and answer key. Clues cover acute, obtuse, and right angles, parallel lines, points, and rays (4.G.1).
Curriculum objectives covered
4.G.1
“Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.”
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.”
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.”
