How Right Angle Calculator Works?
To check whether the given triangle is a right angle, it should satisfy the Pythagoras theorem. Pythagoras derived an important formula for a right triangle. The formula states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
(Hypotenuse)2 = (Base)2 + (Altitude)2
Let us understand this with the help of the following example.
Solved Examples on Right Angle Calculator
Example 1:
Check whether the triangle is a right angle if the hypotenuse is 5 units and base of the triangle is 4 units and the altitude of the triangle is 3 units and verify it using the right angle calculator?
Solution:
Given: Hypotenuse = 5 units, the base of the triangle = 4 units, and the altitude of the triangle = 3 units
To check the given triangle is a right angle, it should satisfy (Hypotenuse)2 = (Base)2 + (Altitude)2
(5)2 = (4)2 + (3)2
25 = 16 + 9
25 = 25
Therefore, the given triangle is right angle.
Example 2:
Check whether the triangle is a right angle if the hypotenuse is 13 units and base of the triangle is 11 units and the altitude of the triangle is 7 units and verify it using the right angle calculator?
Solution:
Given: Hypotenuse = 13 units, the base of the triangle = 11 units, and the altitude of the triangle = 7 units
To check the given triangle is a right angle, it should satisfy (Hypotenuse)2 = (Base)2 + (Altitude)2
(13)2 = (11)2 + (7)2
169 = 121 + 49
169 ≠ 170
Therefore, the given triangle is not right angle.
Now, try the right angle calculator and check for:
- Hypotenuse = 19 units, the base of the triangle = 15 units, and the altitude of the triangle = 13 units
- Hypotenuse = 10 units, the base of the triangle = 6 units, and the altitude of the triangle = 8 units
