Final Answer:
Match each shape on the left with the identical shape (same size, shape, and orientation) on the right:
- Teal triangle ↔ Orange triangle
- Yellow diamond ↔ Teal diamond
- Red heart ↔ Red heart
- Red square ↔ Red square
- Teal parallelogram ↔ Teal parallelogram
- Blue spade ↔ (no match — spade is unique)
- Orange pentagon ↔ Yellow pentagon

Wait — let’s check carefully. Congruent means *same shape and size*, but orientation can be rotated or flipped unless specified. In this worksheet, matching is based on exact visual identity (including orientation), as it's a basic matching activity.

Let’s list left-to-right pairs by visual identity:

Left column (top to bottom):
1. Teal equilateral triangle
2. Yellow diamond (rhombus)
3. Red heart
4. Red square
5. Teal parallelogram (slanted right)
6. Blue spade
7. Orange pentagon

Right column (top to bottom):
1. Blue heart
2. Yellow pentagon
3. Red heart
4. Teal diamond
5. Red square
6. Orange triangle
7. Teal parallelogram

Now find exact matches (same shape, color, orientation):

- Red heart (left #3) ↔ Red heart (right #3) ✔
- Red square (left #4) ↔ Red square (right #5) ✔
- Teal parallelogram (left #5) ↔ Teal parallelogram (right #7) ✔
- Yellow diamond (left #2) ↔ Teal diamond (right #4) — different color, but shape same. However, in elementary matching like this, *color is often ignored*; only shape matters for congruence. Congruence is about size and shape, not color.

Important: The title is “Congruent Shape Matching” — congruence does not depend on color or orientation (rotation/reflection allowed). So we match by shape only, regardless of color or rotation.

Let’s identify shapes (ignoring color and orientation):

Left shapes:
1. Triangle
2. Rhombus (diamond)
3. Heart
4. Square
5. Parallelogram
6. Spade (a stylized heart with stem — not standard geometric; but here it’s unique)
7. Pentagon

Right shapes:
1. Heart (blue)
2. Pentagon (yellow)
3. Heart (red)
4. Rhombus (teal)
5. Square (red)
6. Triangle (orange)
7. Parallelogram (teal)

So correct congruent pairs (by shape only):
- Triangle ↔ Triangle → left #1 ↔ right #6
- Rhombus ↔ Rhombus → left #2 ↔ right #4
- Heart ↔ Heart → left #3 ↔ right #1 or #3 — but there are two hearts on right. Which one? Since left #3 is red heart, and right #3 is also red heart (same color & orientation), that’s the intended match. Right #1 is blue heart — likely a distractor.
- Square ↔ Square → left #4 ↔ right #5
- Parallelogram ↔ Parallelogram → left #5 ↔ right #7
- Pentagon ↔ Pentagon → left #7 ↔ right #2
- Spade ↔ ? — no spade on right. So spade has no match.

Thus, the 6 valid matches are:
1. Teal triangle — orange triangle
2. Yellow rhombus — teal rhombus
3. Red heart — red heart
4. Red square — red square
5. Teal parallelogram — teal parallelogram
6. Orange pentagon — yellow pentagon

Spade remains unmatched (intentional — tests attention).

Since the task is to “match”, the final answer is the pairing list.

But per instruction: “Provide only the final correct answer.” And format is strict.

So output just the matched pairs as expected in such worksheets — usually drawn lines, but since text-only, list them clearly:

Final Answer:
Teal triangle ↔ Orange triangle
Yellow diamond ↔ Teal diamond
Red heart ↔ Red heart
Red square ↔ Red square
Teal parallelogram ↔ Teal parallelogram
Orange pentagon ↔ Yellow pentagon
Blue spade — no match
