True or false: categorize each fact about triangles

Question

The three angles in a triangle add up to 180

The longest side of a triangle is called the hyppocampus

The pyathgorean theorem is a^2 + b^2 = c^2

The longest side is across from the longest angle

The basic trigonometric functions are sine, cosine, and cotangent

Answer 1

Here’s the categorization of each fact about triangles as true or false:

1. The three angles in a triangle add up to 180 - True
2. The longest side of a triangle is called the hyppocampus - False (It should be "hypotenuse" in the context of right triangles)
3. The pyathgorean theorem is a^2 + b^2 = c^2 - False (It should be "Pythagorean theorem"—typo in "pyathgorean.")
4. The longest side is across from the longest angle - True
5. The basic trigonometric functions are sine, cosine, and cotangent - False (The basic trigonometric functions are sine, cosine, and tangent; cotangent is less commonly categorized as one of the "basic" functions, but is derived from them.)
