Question

suppose a triangle has 3 4 and 6. Which of the following must be true?

Answer 1

What are the options?

Answer 2

Well at least they can be the sides of a triangle :)

Answer 3

all the angles are different

Answer 4

If you wanna check if it is an acute, obtuse, or right triangle check these:

ACUTE:

\( \color{Black}{\Rightarrow a^2 + b^2 > c^2}\)

OBTUSE:

\( \color{Black}{\Rightarrow a^2 + b^2 < c^2 }\)

RIGHT:

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

c is the longest side.

Answer 5

well the options are
1. The triangle in question is not a right triangle
2.The triangle in question is a right triangle
3.the triangle in question May or may not be a right triangle

Answer 6

Awwyea I was correct

Answer 7

Check if \(3^2 + 4^2 = 6^2\)

Answer 8

ok

Answer 9

3^2 + 4^2 =/</> 6^2
9 + 16 =/</> 36
25 =/</> 36

25 < 36

25 is less than 36, so the triangle is obtuse. Option 1 is correct.
