Question

Carlos calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle is it?

Answer 1

Answer:

The first triangle

Step-by-step explanation:

The Pythagoras theorem is used to calculate the side length of the right angle triangle.

The theorem says that the sum of the square of the two shorter legs of a right angle is equal to the square of the hypotenuse.

From the given triangles, the only one which is a right angle triangle is the one with side lengths 2 and 3 .

The first triangle from left to right.

Answer 2

For this case, we have that by definition, the Pythagorean theorem can only be applied to rectangular triangles.

The Pythagorean theorem states that:

$a ^ 2 + b ^ 2 = c ^ 2$

Where:

a, b: are the legs

c: it is the hypotenuse.

In this case the rectangle triangle is in option A.

Answer:

Option A
