# What is the 30 60 90 Triangle Theorem?

## What is the 30 60 90 Triangle Theorem?

In a 30°−60°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg. To see why this is so, note that by the Converse of the Pythagorean Theorem, these values make the triangle a right triangle.

**How do you use the 30 60 90 Triangle Theorem?**

It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle. The hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle.

**What is the rule for a 30 60 90 Triangle to go from the short side to the hypotenuse?**

When the hypotenuse of a 30-60-90 triangle is given, divide that length by 2 to get the shorter side. Multiply the shorter side by the square root of 3 to get the longer side.

**What is the 30 60 90 day plan?**

A 30-60-90 day plan is a document that maps out a new employee’s goals and strategies within the first 90 days of a new job. The plan consists of manageable milestones that are tied to an employee’s position. For a new employee, the plan will help you maximize your work output and productivity in the first 90 days.

**Which triangle is a 30 60 90 triangle quizlet?**

What is right triangle is a triangle with angle measures of 30°, 60°, and 90°. In a 30°-60°-90° right triangle, the measure of the hypotenuse is twice the measure of the short leg, and the measure of the longer leg is the measure of the short leg times √3 . You just studied 2 terms!

**How many triangles are possible having angles 60 90 and 30 a only one B None C Infinite D only 3?**

Infinite triangles are possible having 60° , 90° and 30°. The angles of the prescribed triangle are 60°,30° and 90° which makes 180°,when we combine them. So,it will be a valid triangle if we go with the given angles.

## What is the formula for a 30 60 90 triangle?

The ratio of the sides follow the 30-60-90 triangle ratio: 1 : 2 : √3 1 : 2 : 3. Short side (opposite the 30 30 degree angle) = x x. Hypotenuse (opposite the 90 90 degree angle) = 2x 2 x. Long side (opposite the 60 60 degree angle) = x√3 x 3.

**What are the rules for 30 60 90 triangles?**

– The side opposite to the 30° angle, DE = y = 2 – The side opposite to the 60° angle, BC = y √ 3 = 2 √ 3 – The side opposite to the 90° angle, the hypotenuse AC = 2y = 2 × 2 = 4

**What are the 30 60 90 triangle rules?**

What is the 30 60 90 triangle rule? In a 30°−60°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg. To see why this is so, note that by the Converse of the Pythagorean Theorem, these values make the triangle a right triangle.

### What are the properties of a 30 60 90 triangle?

The most important rule to remember is that this special right triangle has one right angle and its sides are in an easy-to-remember consistent relationship with one another – the ratio is a : a√3 : 2a. Also, the unusual property of this 30 60 90 triangle is that it’s the only right triangle with angles in an arithmetic progression.
