Introduction

In geometry, a 30-60-90 triangle is a special right-angled triangle with angles measuring 30, 60, and 90 degrees. These triangles have unique properties that make them useful in various mathematical and real-world applications. In this article, we will explore the properties of 30-60-90 triangles and determine the possible ratio of the length of the longer leg to the length of the hypotenuse.

Properties of 30-60-90 Triangles

A 30-60-90 triangle has several distinct properties that can be used to find the ratio of the length of the longer leg to the length of the hypotenuse. The properties of a 30-60-90 triangle are as follows:

The ratio of the length of the shorter leg to the length of the hypotenuse is 1:2.
The ratio of the length of the longer leg to the length of the hypotenuse is 1:√3.
The ratio of the length of the shorter leg to the length of the longer leg is 1:√3.

Determining the Ratio of the Longer Leg to the Hypotenuse

To determine the ratio of the length of the longer leg to the length of the hypotenuse, we can use the properties of a 30-60-90 triangle. The ratio of the length of the longer leg to the length of the hypotenuse is 1:√3. This means that the length of the longer leg is equal to the length of the hypotenuse multiplied by √3.

Analyzing the Options

Now that we have determined the ratio of the length of the longer leg to the length of the hypotenuse, we can analyze the options provided.

Option A: √3: √3. This option is incorrect because the ratio of the length of the longer leg to the length of the hypotenuse is 1:√3, not √3: √3.
Option B: √3: 2. This option is incorrect because the ratio of the length of the longer leg to the length of the hypotenuse is 1:√3, not √3: 2.
Option C: √2: 2. This option is incorrect because the ratio of the length of the longer leg to the length of the hypotenuse is 1:√3, not √2: 2.

Conclusion

In conclusion, the ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse is 1:√3. This means that the length of the longer leg is equal to the length of the hypotenuse multiplied by √3. Therefore, the correct option is not listed among the provided choices.
