Question

will fan/metal.
Determine whether each set of numbers can be measure of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right.

Answer 1

10, 11, 20

Answer 2

Determine whether each set of numbers can be measure of the sides of a triangle.

Use the Triangle Inequality Theorem:

One side of a triangle has measure less than the sum of the other two.

Answer 3

so if the third number is less than the sum of the other two, it is a triangle?

Answer 4

10, 11, 20

Is 10 < 11 + 20 ?

Is 11 < 10 + 20 ?

Is 20 < 10 + 11 ?

You need 3 yeses to go to the next step.

Answer 5

so that is a triangle

Answer 6

and how do i figure out what type of triangle

Answer 7

Any side could be the third side. That is why there are three questions to consider before declaring those as sides of triangles.

Answer 8

ooh, and then you use my pythagorean theorem to find out if its acute, obtuse, or right? correct?

Answer 9

yeah!

Answer 10

thanks!

Answer 11

If the square of the length of the longest side of a triangle is less than the sum of the squares of the lengths of the other two sides, then the triangle is an acute triangle.

Answer 12

If the square of the length of the longest side of a triangle is greater than the sum of the squares of the lengths of the other two sides, then the triangle is an obtuse triangle.

Answer 13

If the square of the length of the longest side of a triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.

Answer 14

thanks dude!

Answer 15

20^2 < 10^2 + 11^2

So, what kind of triangle is it? @kaitlyn_nicole

Answer 16

ummm, acute?

Answer 17

because 400 < 244 is incorrect

Answer 18

Acute. yes.

Answer 19

thanks!

Answer 20

You are welcome.
