Recognizing special right triangles in geometry can help you to answer some questions quicker.
There are two types of special right triangles and they have the following properties:
In this triangle, the important thing to remember is that the legs have equal length.
Formula: Hypotenuse = √(2)×(Leg)
Long Leg = (√3) × (Short Leg)
Hypotenuse = 2. short leg
You can also use the Pythagorean theorem, but if you can see that it is a special triangle it can save you some calculations.
