Grade 4 easy practice introduces the main quadrilaterals: square, rectangle, rhombus, parallelogram, and trapezoid. Students name shapes from descriptions of sides and angles, build vocabulary, and answer short-answer prompts about why squares belong to multiple families on this beginner CCSS 4.G.2 worksheet. Students sort common shapes and write definitions in their own words while building a strong foundation for Grade 4 geometry vocabulary work.

Classifying Quadrilaterals
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A square has 4 equal sides but no right angles.
Rewrite: A square has 4 equal sides and 4 right angles.
2. Fix the sentence:
A rectangle has 4 equal sides always.
Rewrite: A rectangle has 4 right angles, with opposite sides equal.
3. Fix the sentence:
A trapezoid has two pairs of parallel sides.
Rewrite: A trapezoid has exactly one pair of parallel sides.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A quadrilateral with 4 equal sides and 4 right angles is a square.
2. A four-sided shape with exactly one pair of parallel sides is a trapezoid.
3. A parallelogram with 4 equal sides but no right angles is a rhombus.
4. A quadrilateral with two pairs of parallel sides is called a parallelogram.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why is every square also a rectangle?
A square is a rectangle because it has 4 right angles, which is the rule for rectangles. A square also has 4 equal sides, making it a special rectangle.
2. How can you tell a rhombus from a square?
Both have 4 equal sides. A square also has 4 right angles, but a rhombus does not need right angles. So a tilted rhombus is not a square.
