Question

Ross calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle was it? Four triangles E, F, G, H are shown from left to right. Triangle E has two sides labeled 2 each, and the included acute angle is shown. Triangle F has one side labeled as 2 and the other as 3, and the included right angle is shown. Triangle G has one side labeled as 4 and the other as 2, and the included obtuse angle is shown. Triangle H has one side labeled as 6 and the other as 7, and the included acute angle is shown. E F G H Question 4(Multiple Choice Worth 5 points)

Answer 1

The Pythagorean theorem only applies to right triangles. The appropriate choice is
  F

Answer 2

Answer: Triangle F

Step-by-step explanation: To calcutale the Pythagorean Theorem you must need the following below:

1. A^2 + B^2 = C^2

2. Right Traingle

Fot this particular problem the question's asking which traingle did Ross use to sovle for the Pythagorean Theorem.  Looking back at the infromation provided to sovle for the Pythagorean Theorem you would need a right triangle. A right triangle or right-angled triangle is a triangle in which one angle is a right angle. If you look back at your answer options you can automaticly eliminate traingles E, G, and H. Triangles E, G, and H dont contain right angles, which are needed to solve for the Pythagorean Theorem. This mean's, you would be left with Traingle F which contains an right angle, which would be suitable for solving for Pythagorean Theorem.

Hope this helps :D
