These triangles have angles of 30 degrees, 60 degrees, and 90 degrees, with side ratios of 1 : √3 : 2. Whether you’re a student solving homework problems, an engineer working on designs, or a hobbyist exploring math concepts, this calculator provides accurate results in seconds.

Primary keywords like “30 60 90 triangle calculator” and “30-60-90 triangle side calculator” are optimized here to help you find us easily on search engines. We focus on delivering precise computations for triangle sides, helping users understand the unique properties of these special right triangles.

This tool stands out by offering instant calculations without the need for manual formulas, making it ideal for quick references. Secondary keywords such as “right triangle calculator” and “trigonometry calculator” ensure we cover related searches, while long-tail keywords like “how to calculate sides of a 30 60 90 triangle online” target users with specific intents.

How It Works: Simple 3-Step Explanation

1. Select the side type you know: opposite 30°, opposite 60°, or hypotenuse.
2. Enter the length of that side in the input field.
3. Click “Calculate” to instantly get the lengths of the other two sides.

Using the standard 30-60-90 triangle ratios, our calculator applies the formulas seamlessly. For example, if you input the shortest side (opposite 30°), it multiplies by √3 for the opposite 60° side and by 2 for the hypotenuse.

30 60 90 Triangle Formula

The core formula for a 30-60-90 triangle is based on the side ratios: if the side opposite the 30° angle is x, then the side opposite 60° is x√3, and the hypotenuse is 2x. This derives from trigonometric principles where sin(30°) = 1/2, sin(60°) = √3/2, and cos(30°) = √3/2.

Formulas:

• Hypotenuse = 2 × (opposite 30°)
• Opposite 60° = √3 × (opposite 30°)
• Opposite 30° = Hypotenuse / 2

These equations are embedded in our 30 60 90 triangle calculator for seamless use.

Example Calculation

Suppose the side opposite 30° is 5 units. Using the 30 60 90 triangle calculator:

• Opposite 60° = 5 × √3 ≈ 8.66 units
• Hypotenuse = 5 × 2 = 10 units

This example demonstrates how our tool handles real-world inputs, optimized for keywords like “30 60 90 triangle example problems.”

Limitations of the 30 60 90 Triangle Calculator

While powerful, this calculator assumes perfect 30-60-90 angles and doesn’t account for real-world imperfections like measurement errors. It only computes sides, not areas or perimeters directly. For advanced needs, consider combining with other tools.
