Answer Key & Explanations

Identify 2D Shapes · Kindergarten · Worksheet 2

  1. Look at the shape with 3 straight sides and 3 corners. Which shape is it? Answer: D. Triangle Solution: A square has 4 straight sides and 4 corners A circle has 0 straight sides and 0 corners A triangle has 3 straight sides and 3 corners A rectangle has 4 straight sides and 4 corners The shape with 3 straight sides and 3 corners is a triangle, so the correct answer is Triangle.
    Full step-by-step solution

    Step 1: A square has 4 straight sides and 4 corners Step 2: A circle has 0 straight sides and 0 corners Step 3: A triangle has 3 straight sides and 3 corners Step 4: A rectangle has 4 straight sides and 4 corners The shape with 3 straight sides and 3 corners is a triangle, so the correct answer is Triangle.

  2. Which shape has 4 equal sides? Answer: B. Square Solution: A square has 4 sides that are all equal in length A rectangle has 4 sides but opposite sides are equal, not all sides A triangle has 3 sides, not 4 sides The correct answer is Square.
    Full step-by-step solution

    Step 1: A square has 4 sides that are all equal in length Step 2: A rectangle has 4 sides but opposite sides are equal, not all sides Step 3: A triangle has 3 sides, not 4 sides Step 4: A circle has no straight sides The correct answer is Square.

  3. Which shape has exactly 3 sides and 3 corners? Answer: B. Triangle Solution: A square has 4 sides and 4 corners A rectangle has 4 sides and 4 corners A triangle has 3 sides and 3 corners A pentagon has 5 sides and 5 corners The shape with exactly 3 sides and 3 corners is a triangle, so the correct answer is Triangle.
    Full step-by-step solution

    Step 1: A square has 4 sides and 4 corners Step 2: A rectangle has 4 sides and 4 corners Step 3: A triangle has 3 sides and 3 corners Step 4: A pentagon has 5 sides and 5 corners The shape with exactly 3 sides and 3 corners is a triangle, so the correct answer is Triangle.

  4. Lily is playing with her blocks. She finds a block that has 4 equal sides and 4 corners. What shape is Lily's block? Answer: A. Square Solution: A square has 4 equal sides and 4 corners. A triangle has 3 sides and 3 corners. A circle has 0 sides and 0 corners.
    Full step-by-step solution

    Step 1: A square has 4 equal sides and 4 corners. Step 2: A triangle has 3 sides and 3 corners. Step 3: A circle has 0 sides and 0 corners. Step 4: A rectangle has 4 sides and 4 corners, but its sides are not all equal. Since Lily's block has 4 equal sides and 4 corners, it must be a square. The correct answer is Square.
