Question

The Pythagorean theorem can be used to find a missing length of any triangle.

True
False

Answer 1

What do u think what is the answer?

Answer 2

True

Answer 3

For an example

Answer 4

correct @Here_to_Help15

Answer 5

So you would apply the Pythagorean Theorem
\[a^{2} + b^{2} = c^{2}\]

Answer 6

c^{2} would be your hypotenuse

Answer 7

Since you have the hypotenuse and a leg you would subtract

Answer 8

pythagorean theorem is used for a right angle triangle

Answer 9

Yes thanks for that :)

Answer 10

SO in this case
\[a^{2} + 9^{2} = 15^{2}\]

Answer 11

I don't like this question seems misleading you can make a right angle then use similar figures etc to apply the theorem

Answer 12

Im misleading?

Answer 13

@Here_to_Help15 what you have is correct using the right angle triangle but the question posted said ANY triangle

Answer 14

oh 0.0

Answer 15

I didn't catch that

Answer 16

So i spoke to soon

Answer 17

it was using pythagorean theorem that we derived the cosine rule for solving triangles and the sin rule
