How to Calculate Right Angle Triangle?
A right-angle triangle is having 3 sides the base, altitude, and hypotenuse. The angle formed by the joining point of altitude and the base is 90°. A right-angle triangle follows Pythagoras Theorem.

The Pythagoras Theorem formula for a right angle triangle is: Hypotenuse2 = Base2 + Altitude2
Let's learn through an example how to find a triangle is a right angle triangle or not.
Solved Example :
If the three sides of a triangle are 13 units, 12 units, and 5 units. Calculate if the triangle formed is a right-angle triangle or not.
The longest side of the triangle is the hypotenuse that is, Hypotenuse = 13 units
The other two sides are: Base = 12 units and Altitude = 5 units
Now apply the Pythagoras theorem and if the Pythagoras theorem formula satisfies then the triangle is a right-angled triangle.
Hypotenuse2 = Base2 + Altitude2
132 = 122 + 52
169 = 144 + 25
169 = 169
Since the Pythagoras theorem satisfies, therefore the triangle is a right angle triangle.
Now, use our online Right Angle Triangle calculator and find if the triangle is right angle triangle or not whose sides are:
1) 15 units, 5 units, and 10 units
2) 25 units, 24 units, and 7 units
