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. One of the key properties of 30-60-90 triangles is the ratio of the lengths of their sides. In this article, we will explore the possible ratios of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse.

Understanding 30-60-90 Triangles

A 30-60-90 triangle is a right-angled triangle with one angle measuring 30 degrees and the other angle measuring 60 degrees. The side opposite the 30-degree angle is called the shorter leg, and the side opposite the 60-degree angle is called the longer leg. The side opposite the 90-degree angle is called the hypotenuse.

Properties of 30-60-90 Triangles

One of the key properties of 30-60-90 triangles is the ratio of the lengths of their sides. The ratio of the lengths of the sides of a 30-60-90 triangle is always 1:√3:2. This means that the ratio of the length of the shorter leg to the length of the longer leg is 1:√3, and the ratio of the length of the longer leg to the length of the hypotenuse is 1:2.

Possible Ratios of the Longer Leg to the Hypotenuse

Given the properties of 30-60-90 triangles, we can determine the possible ratios of the length of the longer leg to the length of the hypotenuse. Since the ratio of the length of the longer leg to the length of the hypotenuse is 1:2, we can express this ratio as a fraction: 1/2.

Checking the Options

Now, let's check the options provided to see which ones match the possible ratios of the length of the longer leg to the length of the hypotenuse.

Option A: 2: 2√2

This option does not match the possible ratio of the length of the longer leg to the length of the hypotenuse. The ratio 2: 2√2 is not equal to 1:2.

Option B: 1: √2

This option does not match the possible ratio of the length of the longer leg to the length of the hypotenuse. The ratio 1: √2 is not equal to 1:2.

Option C: 1: 2

This option matches the possible ratio of the length of the longer leg to the length of the hypotenuse. The ratio 1: 2 is equal to 1:2.

Conclusion

In conclusion, the possible ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse is 1:2. This ratio is a fundamental property of 30-60-90 triangles and is useful in various mathematical and real-world applications.

Final Answer

The final answer is:

Option C: 1: 2
