Given:
Given that a triangle has side lengths 1.5 inches, 2 inches and 3 inches.
We need to determine whether the triangle is a right triangle.
Right triangle:
To determine whether the given triangle is a right triangle, let us use the Pythagorean theorem.
Since, the value of the hypotenuse takes the largest value in the given triangle, then from the given sides, the hypotenuse is 3 inches.
The legs of the triangle are 1.5 inches and 2 inches.
Applying the Pythagorean theorem, we have;
![3^2=1.5^2+2^2](https://img.qammunity.org/2021/formulas/mathematics/college/n464wfikjao77cu8i9gaxrib2277220o4w.png)
Squaring the terms, we have;
![9=2.25+4](https://img.qammunity.org/2021/formulas/mathematics/college/sug4jrz9n6rfqbp7ks99uditdv2lgy4vs6.png)
![9 \\eq 6.25](https://img.qammunity.org/2021/formulas/mathematics/college/xsuafyjq5hohtgsdh7sxbvzb3oc4bytr4i.png)
Since, both sides of the equation are not equal, then the given triangle with sides 1.5 inches, 2 inches and 3 inches is not a right triangle.
