Grade 4 easy follow-up practice asks students to sort quadrilaterals by counting parallel sides, equal sides, and right angles. Through fill-ins, sentence corrections, and short answers, learners distinguish rhombuses from squares and parallelograms from rectangles using clear, side-and-angle reasoning every time. Students count parallel sides, equal sides, and right angles in clear examples, building careful Grade 4 geometry observation and sorting habits.

Classifying Quadrilaterals
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A rhombus must always have right angles.
Rewrite: A rhombus has 4 equal sides but does not need right angles.
2. Fix the sentence:
A parallelogram has 4 right angles always.
Rewrite: A parallelogram has 2 pairs of parallel sides, with no required right angles.
3. Fix the sentence:
A trapezoid has 4 equal sides.
Rewrite: A trapezoid has exactly one pair of parallel sides; sides may differ.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A square has 4 right angles.
2. A parallelogram has 2 pairs of parallel sides.
3. A rhombus has 4 equal sides.
4. A trapezoid has exactly 1 pair of parallel sides.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Name two ways a rectangle and a rhombus are different.
A rectangle has 4 right angles, but a rhombus does not need them. A rhombus has 4 equal sides, but a rectangle only needs opposite sides to be equal.
2. Why is a parallelogram not always a rectangle?
A parallelogram only needs 2 pairs of parallel sides. A rectangle also needs 4 right angles. A slanted parallelogram has parallel sides but no right angles, so it is not a rectangle.
