🔷 Pythagorean Triplet Trick | SSC CGL Geometry Made Easy
Most students spend time calculating…
Top scorers recognize patterns.
In right-angled triangles:
a² + b² = c²
But in exams like SSC CGL, you don’t always need to calculate.
👉 Just remember these powerful triplets:
(3, 4, 5)
(5, 12, 13)
(7, 24, 25)
(8, 15, 17)
💡 Golden Shortcut:
Multiples of these are also triplets
→ (3,4,5) → (6,8,10), (9,12,15)
🔶 Example (SSC Level):
Sides = 8 cm and 15 cm
👉 Direct answer = 17 cm (No calculation!)
🔶 Reverse Trick (Very Important):
If hypotenuse = 25 and one side = 7
👉 Second side = 24
🎯 Key Takeaway:
Don’t just solve questions — train your brain to recognize patterns.
Because in competitive exams,
👉 Speed + Smart Work = Selection

🔷 Triangle Ratio Trick | SSC CGL Geometry Shortcut

Many students struggle with triangle questions because they rely only on formulas…
But smart learners use ratios to solve instantly.
🔹 30°–60°–90° Triangle Trick
👉 The sides are always in the ratio:
1 : √3 : 2
Opposite 30° → smallest side
Opposite 60° → √3 times
Hypotenuse → double of smallest side
🔶 Quick Example:
If hypotenuse = 10 cm
👉 Smallest side = 5 cm
👉 Other side = 5√3 cm
(No lengthy calculation needed!)
🔶 Reverse Trick:
If smallest side = 7
👉 Hypotenuse = 14
👉 Other side = 7√3
🎯 Why This Matters?
In exams like SSC CGL, saving even 10–15 seconds per question can boost your rank significantly.
💡 Key Takeaway:
👉 Don’t calculate everything
👉 Recognize the pattern and solve faster

Angle देखो, ratio लगाओ, answer पाओ!”
👉 “Smart work > Hard work in SSC”
जब भी 30° दिखे:
Direct ratio सोचो, equation कम बनाओ
Equation बनाओ मत, pattern पहचानो!”
