Key Triangle Formulas Used

To understand how the calculator works, it is important to know the basic formulas behind triangle geometry.

1. Area of a Triangle

$A = \frac{1}{2}bh$A=21​bh

$b$b

$h$h

$A = \frac{1}{2} b h \approx 24.00$A=21​bh≈24.00b = 8.0h = 6.0

Where:

• A = Area
• b = Base
• h = Height

---

2. Pythagorean Theorem (Right Triangle)

$a^2 + b^2 = c^2$a2+b2=c2

$a$a

$b$b

$c = \sqrt{a^2 + b^2} \approx 21.21$c=a2+b2​≈21.21

$a^2 + b^2 = c^2 \approx 225.00 + 225.00 = 450.00$a2+b2=c2≈225.00+225.00=450.00abc

Where:

• c = Hypotenuse
• a, b = Other two sides

How the Geometry Triangle Calculator Works

The calculator uses geometric principles to determine missing values. Depending on the inputs provided, it applies the correct formula automatically.

For example:

• If base and height are given → it calculates area
• If two sides of a right triangle are given → it finds the third side
• If all sides are known → it calculates perimeter and checks validity

This automation eliminates the need for manual formula selection.
