## What is the shortest side of a 30 60 90 Triangle?

In any triangle, the side opposite the smallest angle is always the shortest, while the side opposite the largest angle is always the longest.

You can see how that applies with to the 30-60-90 triangle above.

Triangles with the same degree measures are similar and their sides will be in the same ratio to each other..

## What is the formula for a 90 degree triangle?

Right Triangles and the Pythagorean Theorem. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.

## What is the length of the hypotenuse of a 45 45 90 Triangle?

The hypotenuse’s length can be found by multiplying the leg’s length by sqrt(2). Tis triangle’s hypotenuse has a length of 16 units. In a 45-45-90 triangle, both of the legs have the same length and the ratio of one leg to the hypotenuse is 1:sqrt(2). I hope this helps!

## What is the formula for 30 60 90 Triangle?

The first concept of a 30-60-90 triangle is the pattern of x, x√3,2x which Sal represents as a ratio of 1, √3, 2. Using the Pythagorean Theorem, (1)^2 + (√3)^2 = (2)^2 or 1 + 3 = 4. This ratio will be true of every 30-60-90 triangle. The second concept is to find the other sides if you know one of the sides is 1.

## What is the formula for any triangle?

So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

## What is a 45 degree triangle?

A 45 – 45 – 90 degree triangle (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of. Note that it’s the shape of half a square, cut along the square’s diagonal, and that it’s also an isosceles triangle (both legs have the same length).

## What does 90 degrees look like?

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. … The term is a calque of Latin angulus rectus; here rectus means “upright”, referring to the vertical perpendicular to a horizontal base line.

## How do you find the missing side of a 30 60 90 Triangle?

A Quick Guide to the 30-60-90 Degree TriangleType 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. … Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. … Type 3: You know the long leg (the side across from the 60-degree angle).

## What is the formula for a 45 45 90 Triangle?

Using the pythagorean theorem – As a right angle triangle, the length of the sides of a 45 45 90 triangle can easily be solved using the pythagorean theorem. Recall the pythagorean theorem formula: a 2 + b 2 = c 2 a^2+b^2=c^2 a2+b2=c2.

## What is another name for a 45 45 90 Triangle?

The diagonal of a square becomes hypotenuse of a right triangle and the other two sides of a square becomes the two sides (base and opposite) of a right triangle. The 45°-45°-90° right triangle is also sometimes referred as an isosceles right triangle because it has two equal side lengths and two equal angles.

## What are the sides of a 30 60 90 Triangle?

A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its side lengths are always in the ratio of 1: √3:2.

## Is a right angle 45 degrees?

An angle can be measured using a protractor, and the angle of measure 90 degrees is called a right angle. … When the right angle is divided into two equal parts each angle measures 45°.

## What is the height of a 45 45 90 Triangle?

Explanation: If the hypotenuse of a 45-45-90 right triangle is then: The height and the base of the triangle will be the same length since it is a 45-45-90 triangle (isosceles).

## How many triangles are possible having angles 60 90 and 30?

They’re most definitely congruent. Now that we’ve proven the congruencies of the two new triangles, we can see that the top angles must each be equal to 30 degrees (because each triangle already has angles of 90° and 60° and must add up to 180°). This means we have made two 30-60-90 triangles.
