Question

Which of the following are measurements of the sides of a right triangle?

A. 10, 8, 6

B. 13, 12, 5

C. 26, 24, 10

D. all of the above

Answer 1

All of them lol..

Answer 2

how so?

Answer 3

\(\Large \color{MidnightBlue}{\Rightarrow a^2 + b^2 = c^2 }\)

c is the longest side.

Answer 4

all

Answer 5

The formula I stated is called Pythagorean theorem.

Answer 6

@CarmelGirlKatie47 Good work :) I like you asking 'Why'

Answer 7

phrthagren therum
i spelt that rong but close

Answer 8

haha lol miranda

Answer 9

A2+b2 =c2

Answer 10

You get that carmel?

Answer 11

sorry my computer was lagging. yeah i did. i just didn't understand where all the other numbers came from lol. but thank you i got it now.

Answer 12

parth your a lifesaver. fanning you.

Answer 13

Let me try it with 6,8,10 for you.


\(\Large \color{MidnightBlue}{\Rightarrow 6^2 + 8^2 = 10^2 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 36 + 64 = 100 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 100 = 100 \checkmark }\)

Answer 14

do they all have to equal out 100? what do they all have that are similar?

Answer 15

No, I mean that when you set up an equation like that, the values you get are equal. If they are not, then they can't be a right triangle.

Answer 16

oh i see. okay so they all have to be congruent to each other?

Answer 17

Let's try it with 5,12,13:

\(\Large \color{MidnightBlue}{\Rightarrow 5^2 + 12^2 = 13^2 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 25 + 144 = 169 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 169 = 169 }\)
This tells that they can be sides of a right angled triangle.

Answer 18

Okay, give me three numbers, I'll test if they can be sides of a right triangle.

Answer 19

9, 21, 19

Answer 20

are all the numbers squared?

Answer 21

Okay, the normal equation for testing this is:

\(\Large \color{MidnightBlue}{\Rightarrow a^2 + b^2 = c^2 }\)
c is the largest number. If the equation is satisfied, then they can be.

\(\Large \color{MidnightBlue}{\Rightarrow 9^2 + 19^2 = 21^2 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 81 + 361 = 441 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 442 \ne 441 }\)
They can't be the three sides.

Answer 22

do they have to be in the bounderies of 360? 30+60+90

Answer 23

I'm not sure what you just meant by that.

Answer 24

Just keep it simple. When you are given three numbers and asked if they can be the three sides of a right-angled triangle, then just test it with that equation.

Answer 25

Remember that c is the largest number.

Answer 26

im starting to understand this, let me try one on my own.

Answer 27

Message me if you have any confusion :D

Answer 28

okay so for this one i got none of the above. because they didn't equal with C


Which of the following are measurements of the sides of a right triangle?

A. 101, 99, 20

B. 28, 26, 12

C. 17, 14, 6

D. none of the above

Answer 29

A. works
