Carlos calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle is it? (5 points)
Four triangles A, B, C, D are shown from left to right. Triangle A has a side labeled as 2 and another side labeled as 3, and the included right angle is shown. Triangle B has one side labeled as 3 and the other as 6 and the included obtuse angle is shown. Triangle C has one side labeled as 2 and the other also as 2 and the included acute angle is shown. Triangle D has one side labeled as 6 and the other as 7, and the included acute angle is shown.
A
B
C
D
To determine which triangle Carlos calculated the missing side length for using the Pythagorean Theorem, we need to look for a triangle with two known side lengths and a right angle.
Triangle A has side lengths labeled as 2 and 3, and also includes a right angle. Therefore, Carlos most likely used the Pythagorean Theorem to calculate the missing side length for Triangle A.
