• Rectangle = 2 × (length + width)
• Triangle = a + b + c

🔹 Area Formulas

• Square = side²
• Rectangle = length × width
• Triangle = ½ × base × height

🔺 2. Triangle Formulas

Triangles are one of the most important topics in geometry.Class 10 Geometry Formulas List

🔹 Area of Triangle

• Area = ½ × base × height

🔹 Heron’s Formula

• s = (a + b + c) / 2
• Area = √[s(s − a)(s − b)(s − c)]

🔹 Pythagoras Theorem

In a right-angled triangle:

• Hypotenuse² = Base² + Perpendicular²

⚪ 3. Circle Formulas

Circle-based questions are very common in exams.

🔹 Circumference of Circle

• C = 2πr

🔹 Area of Circle

• A = πr²

🔹 Diameter

• d = 2r

📦 4. Surface Area and Volume Formulas

🔹 Cube

• Volume = a³
• Surface Area = 6a²

🔹 Cuboid

• Volume = length × width × height
• Surface Area = 2(lw + lh + wh)

🔹 Cylinder

• Volume = πr²h
• Curved Surface Area = 2πrh

📏 5. Coordinate Geometry Formulas

🔹 Distance Formula

• √[(x₂ − x₁)² + (y₂ − y₁)²]

🔹 Midpoint Formula

• ((x₁ + x₂)/2 , (y₁ + y₂)/2)

📊 6. Basic Trigonometry Formulas

🔹 Trigonometric Ratios

• sinθ = Perpendicular / Hypotenuse
• cosθ = Base / Hypotenuse
• tanθ = Perpendicular / Base
