Some More Interesting Puzzles

Brain-Teaser 14 | Matchstick Puzzles, Geometry, Shading & Triangles | Key To Enjoy Learning Maths

🧠 Some More Interesting Puzzles

🐟 CHANGING DIRECTION
🐟 Can you change the travelling direction of this fish by removing the position of any two matches?
πŸ’‘ Solution: Move two matchsticks to make the fish face the opposite direction
πŸ’‘ Matchstick puzzles develop spatial reasoning and creative problem-solving skills!
➕ CORRECT THE EQUATION
➕ Correct the equation by removing only one matchstick.
πŸ’‘ Solution: Remove one matchstick to make the equation mathematically correct
πŸ’‘ Tip: Look for numbers that can become different numbers by removing one matchstick (like 6 becoming 5, or 9 becoming 5, or + becoming -).
πŸ”² 361 MATCHSTICKS = ? SQUARES
πŸ”’ 361 matchsticks can make _____ squares.
πŸ“ Pattern:
1 square → 4 matchsticks
2 squares → 7 matchsticks
3 squares → 10 matchsticks
Rule: 3a + 1 where a = number of squares

3a + 1 = 361
3a = 360
a = 120 squares
✅ 361 MATCHSTICKS CAN MAKE 120 SQUARES
πŸ’‘ This pattern shows how matchsticks increase linearly with the number of squares arranged in a row.
🎨 SHADE 1/3 OF THE SQUARE
🟦 Shade 1/3 of the given square (9×9 grid)
πŸ“ Solution:
Separate square as 9 × 9 = 81 small squares
Shaded part = 81 × 1/3 = 27 squares
✅ Shade 27 small squares
🟦 Shade 1/3 of the given square (3×3 grid)
πŸ“ Solution:
Separate square as 3 × 3 = 9 small squares
Shaded part = 9 × 1/3 = 3 squares
✅ Shade 3 small squares
🟦 Shade 1/3 of the given square (6×6 grid)
πŸ“ Solution:
Separate square as 6 × 6 = 36 small squares
Shaded part = 36 × 1/3 = 12 squares
✅ Shade 12 small squares
πŸ”Ί TRIANGLE GEOMETRY PUZZLES
πŸ“ Draw 2 lines to get 4 congruent triangles
✅ Draw both diagonals of the square → 4 congruent triangles
πŸ“ Draw 4 lines to get 8 congruent triangles
✅ Draw both diagonals + vertical and horizontal center lines → 8 congruent triangles
πŸ“ Draw 3 lines to get 4 congruent triangles
✅ Draw lines connecting midpoints and one diagonal
πŸ“ Draw 5 lines to get 6 congruent triangles
✅ Draw lines from vertices to opposite side midpoints
πŸ“ Draw 2 lines to get 3 congruent triangles
✅ Draw two medians from one vertex
πŸ“ Draw 3 lines to get 6 congruent triangles
✅ Draw the three medians of an equilateral triangle
