Use the image to answer the question.

A triangle has the vertices labeled upper E upper F upper D. The height upper E upper F is labeled 15, the base upper D upper F is labeled 20, and the hypotenuse upper D upper E is labeled 25. Angle upper E measures 60 degrees and angle upper D measures 30 degrees.

Does the Pythagorean Theorem apply to this triangle? How do you know?

No, because the triangle is not a right triangle.
No, because the triangle is not a right triangle.

Yes, because it is a right triangle.
Yes, because it is a right triangle.

No, because the angle at point F is 90°.

Answer 1

Pythagorean theorem only works on right triangles, and the triangle doesn't look like right angled to me. (After the comma I'm not trustworthy.)

Answer 2

Yes, because it is a right triangle.

Answer 3

Apologies for the confusion. You are correct. The Pythagorean Theorem only applies to right triangles, and based on the given information, the triangle in question is not a right triangle. Therefore, the Pythagorean Theorem does not apply to this triangle.
