A triangle has the following side lengths: 8 centimeters, 13 centimeters, 15 centimeters. Which of the following statements best describes its construction? It is impossible to construct a triangle with these side lengths. There is one possible triangle with these side lengths. There are many possible triangles with these side lengths. There are many possible similar triangles with these side lengths.

Answers

Answer:

The statements that best describes its construction is:

There is one possible triangle with these side lengths.

Step-by-step explanation:

We know that with the help of three given angle measures infinite number of triangles could be constructed with different side lengths and with the help of three gives side lengths a unique triangle is constructed.

Here we are given three side lengths as:

8 centimeters, 13 centimeters, 15 centimeters.

This means that there is only one such triangle possible.

I am not completely sure but I would think it would be the second statement. Hopes this helps.

Please help!!!Given the length of three sides of a triangle, which is a right triangle?
(1) 10,26,24
(2) 20,12,18
(3) 30,15,26
(4) 40,50,80

And also explain why it is the answer.

Answers

Pythagorean Theorem: $a^2 + b^2 = c^2$
c represents the longest side of the triangle
If the triangle is a right triangle, the Pythagorean theorem will be true.

(1) 10,24,26
$10^2 + 24^2 = 676$
$26^2 = 676$
$10^2 + 24^2 = 26^2$
Right Triangle

(2) 12,18,20
$12^2 + 18^2 = 468$
$20^2 = 400$
$12^2 + 18^2 \neq 20^2$
Not a right triangle

(3) 15,26,30
$15^2 + 26^2 = 901$
$30^2 = 900$
$15^2 + 26^2 \neq 30^2$
Not a right triangle

(4) 40,50,80
$40^2 + 50^2 = 4100$
$80^2 = 6400$
$40^2+50^2 \neq 80^2$
Not a right triangle

#1 is a right triangle
