Which of the following are true statements about a [tex]$30-60-90$[/tex] triangle?

Check all that apply.

A. The hypotenuse is twice as long as the shorter leg.
B. The longer leg is [tex]$\sqrt{3}$[/tex] times as long as the shorter leg.
C. The hypotenuse is [tex]$\sqrt{3}$[/tex] times as long as the shorter leg.
D. The hypotenuse is [tex]$\sqrt{3}$[/tex] times as long as the longer leg.
E. The hypotenuse is twice as long as the longer leg.
F. The longer leg is twice as long as the shorter leg.



Answer :

To determine which statements about a [tex]\(30-60-90\)[/tex] triangle are true, let's recall the properties of such a triangle. In a [tex]\(30-60-90\)[/tex] triangle:

1. The shorter leg is opposite the [tex]\(30^\circ\)[/tex] angle.
2. The longer leg is opposite the [tex]\(60^\circ\)[/tex] angle.
3. The hypotenuse is opposite the [tex]\(90^\circ\)[/tex] angle.

In this type of triangle:
- The length of the hypotenuse is twice the length of the shorter leg.
- The length of the longer leg is [tex]\(\sqrt{3}\)[/tex] times the length of the shorter leg.

Now let's evaluate each statement:

A. The hypotenuse is twice as long as the shorter leg.
- This is true because, by definition, the hypotenuse is [tex]\(2 \times\)[/tex] the length of the shorter leg.

B. The longer leg is [tex]\(\sqrt{3}\)[/tex] times as long as the shorter leg.
- This is also true, as the longer leg is always [tex]\(\sqrt{3} \times\)[/tex] the length of the shorter leg.

C. The hypotenuse is [tex]\(\sqrt{3}\)[/tex] times as long as the shorter leg.
- This is false. The hypotenuse is [tex]\(2\)[/tex] times the shorter leg, not [tex]\(\sqrt{3}\)[/tex].

D. The hypotenuse is [tex]\(\sqrt{3}\)[/tex] times as long as the longer leg.
- This is false. The ratio of the hypotenuse to the longer leg is [tex]\( \frac{2}{\sqrt{3}} \)[/tex].

E. The hypotenuse is twice as long as the longer leg.
- This is false based on the known properties of the [tex]\(30-60-90\)[/tex] triangle. The hypotenuse is not twice the longer leg.

F. The longer leg is twice as long as the shorter leg.
- This is false. The longer leg is [tex]\(\sqrt{3}\)[/tex] times the shorter leg, not [tex]\(2\)[/tex] times.

Thus, the statements that are true are:
- A. The hypotenuse is twice as long as the shorter leg.
- B. The longer leg is [tex]\(\sqrt{3}\)[/tex] times as long as the shorter leg.

The numerical result reflecting the truth of each statement is:
[tex]\[ (1, 1, 0, 0, 0, 0). \][/tex]
