A protractor is a semicircular disk generally calibrated in degrees and used to measure or construct angles. Explore our assortment of protractor worksheets to become adept at reading this instrument. Encompassing a plethora of practice materials such as an illustratory chart that talks kids through the steps involved in reading a protractor. The radian table includes allows conversion between sexagesimal degrees, centesimal grades (erroneously called centigrade degrees), revolutions, quadrants, and radians in the form of decimals and as fractions of pi. In addition, the chart contains a printable protractor.

Protractorjs

category	detailed task	syntax example
load page	load a page	browser.get('yoururl')
browser btn actions	browser back/forward	browser.navigate().back() OR browser.navigate().forward()
access elements on page See Protractor API list and examples from Protractors test suite	access by angular ngmodel name (must match ngmodel in the html) this is the preferred approach	element(by.model('person.name'));
access by the css id on the page e.g, #user_name (but this can be brittle)	element(by.id('user_name'))
access angular binding to get generated value i.e. for {{}}	element(by.binding('person.concatName'));
access angular repeat list data (must match repeat stmt in the html) See Protractor test suit link for lots more	element.all(by.repeater('person in home.results')); element.all(by.repeater('person in home.results')).count() element.all(by.repeater('person in home.results')).row(0) note: repeater must match that on the page
by text area	element(by.textarea('person.extraDetails'));
by input	element(by.input('username')); element(by.input('username')).clear();
get text from an input	element(by.input('username')).getText() But note: 'There is a webdriver quirk . <input> and <textarea> elements always have empty getText values. Instead, try element.getAttribute('value') .'
access using jquery $ selector ($ is an alias for .by.css) you can use any css selector (but this can be brittle)	$('.class1 .class2');
data entry (entering data, hitting keys etc)	enter data into input hit enter hit tab protractor supports other keys too	element(by.id('user_name')).sendKeys('user1') sendKeys(protractor.Key.ENTER) protractor.Key.TAB
click	click a control such as button, radio	element(by.id('create')).click();
clear a field
is enabled	is the button enabled	element(by.id('create')). isEnabled();

All keys are in /webdriver/key.js including BACK_SPACE, TAB, CLEAR, RETURN, ENTER, SHIFT, SPACE, ESCAPE, arrow up/down/left/right, function keys, numpad etc.
element.all() returns an object as follows: { count : Function, get : Function, first : Function, last : Function, then : Function, each : Function, map : Function }
You made me promises, promises..

• when you call a method on a protractor element you get back a promise e.g. obj.getText()
• protractor expect wraps and handles that promise for you e.g. expect(obj.getText()).toBe('bob')
• if you need to get the result of the promise you could do something like: obj.getText().then(function(text) { var bobIndex = text.indexOf('bob'); })

Protractors are fun and easy to use

Measuring

Protractors usually have two sets of numbers going in opposite directions.

Be careful which one you use!

When in doubt think 'should this angle be bigger or smaller than 90° ?'
