# Why is a circle 360 degrees and not 100?

## Why is a circle 360 degrees and not 100?

Consequently, they divided the circular path into 360 degrees to track each day’s passage of the Sun’s whole journey. An 100-degree circle makes sense for base 10 people like ourselves. But the base-60 Babylonians came up with 360 degrees and we cling to their ways-4,400 years later.

### Which type of catapult is the best?

Among the various types of catapults, the trebuchet was the most accurate and among the most efficient in terms of transferring the stored energy to the projectile.

Are right angles 90 degrees?

Acute angles are less than 90 degrees, obtuse angles are more than 90 degrees, and right angles are exactly 90 degrees.

How far can trebuchets throw?

300 metres

## What angle do you throw the farthest?

45-degree angle

### How many 60 degree angles does it take to make a full turn?

six 60

How many 45 degrees make a full turn?

Eight 45 degree angles

How many 180 degrees angles does it take to make a full turn?

“Doing a 360” means spinning around completely once (spinning around twice is a “720”). “I gave the wheel one complete turn looking for holes” “It completed one cycle”, meaning it went around exactly once….A full rotation is 360 degrees.

Rotations Radians Degrees
¼ π/2 90°
½ π 180°
1 360°
540°

## Why are there 60 minutes in a degree?

In his treatise Almagest (circa A.D. 150), Claudius Ptolemy explained and expanded on Hipparchus’ work by subdividing each of the 360 degrees of latitude and longitude into smaller segments. Each degree was divided into 60 parts, each of which was again subdivided into 60 smaller parts.

### Is a catapult or trebuchet more accurate?

Because “catapult” covers a fairly wide range of machines, it’s accurate to say that trebuchets have a longer range than a catapult when projecting stones at fortifications. When it comes to the maximum range of any catapult, ever, catapults definitely have trebuchets beat.

Is a 90 degree angle straight?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. straight angle-a 180 degree angle.

How many 90 angles does it take to make a full turn?

1 circle = 360 degrees. So, it takes 4 90 degree angles to make a full circle.

## How many 30 degree angles does it take to make a full turn?

12

### Do all circles have 360 degrees?

And they then made a leap and decided to divide this circle on the sky—and all circles—into 360 even parts so that the Sun would move through 1 part per day. Each of these parts was dubbed 1 degree, thus giving us the idea that a circle contains 360 degrees.

Is 360 degrees equal to 0 degrees?

For the purposes of designating a point in the plane, yes, 0 degrees equals 360 degrees.

Why full circle is 360 degrees?

Why Is A Full Circle 360 Degrees, Instead Of Something More Convenient, Like 100? A full circle is 360 degrees because of the Babylonian’s usage of the sexagesimal system, number of days in a year and also because 360 is highly composite.

## How many 120 angles does it take to make a full turn?

Direct link to Kaylen’s post “There are 360 in a full angle. 360/3 = 120. Your a…”

### Which angle is 45 degree?

A straight angle measures 180°. An angle can be measured using a protractor, and the angle of measure 90 degrees is called a right angle. In a right angle, the two arms are perpendicular to each other. When the right angle is divided into two equal parts each angle measures 45°.

How many 45 circ45 ∘ 45 degrees angles does it take to make a full turn?

How many 45 angles does it take to make a full turn? A full turn is 360° there since [Math Processing Error] 45 × 8 = 360 there are eight 45° in a full turn.

Who invented degrees in angles?

Aristarchus of Samos and Hipparchus seem to have been among the first Greek scientists to exploit Babylonian astronomical knowledge and techniques systematically. Timocharis, Aristarchus, Aristillus, Archimedes, and Hipparchus were the first Greeks known to divide the circle in 360 degrees of 60 arc minutes.

## What angle gives the highest height?

60-degrees

### What are the disadvantages of a trebuchet?

Disadvantages. Although trebuchets have greater power and range than catapults, they also have drawbacks. Trebuchets are more complicated than torsion catapults and therefore are plagued by mechanical breakdowns, require more maintenance, more skill to operate and a larger crew.
