What instrument measures angles?
A protractor is a circular or semi circular instrument for measuring angles and some have existed from ancient times. A half circular protractor is marked for 180 degrees and a full circle for 360 degrees. Protractors usually have two sets of numbers going in opposite directions, so be careful which side you use. When in doubt you should ask yourself is the angle greater or smaller that 90 degrees.
How tall is a boy that casts a 4 ft shadow?
The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation: Height = shadow length x tangent of the angle of the sun. Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
How do you measure an angle?
An angle is a measurement of two lines meeting at a common point. The measurement of an angle is recorded in "Degrees". An angle is when a Line "A" and a Line "B" meet at a Point "C". There are four main types of angles:Type A) Acute angleType B) Right angleType C) Obtuse angleType D) Straight angleAn acute angle is an angle that measures between 0 degrees and 90 degrees. A right angle is a 90 degree angle. (Where a vertical Line "A" and a horizontal Line "B" meets at a Point "C".) An obtuse angle is an angle between 90 degrees and 180 degrees. (A straight line) A straight angle is a 180 degree angle. Now that you know the 4 different types of angles, you can now figure out how to measure an angle.As stated above, an angle is a measurement of two lines meeting at a common point. To find the measurement of an angle, you can use either two of the following methods:Method 1) Use a protractor to measure the angleMethod 2) Find a solution based on facts and equations to figure out the angle.(Method 2 uses no type of mathematical tool, such as a protractor to find out the measurement.)Method 1: Using a Protractor.A Protractor is a mathematical tool, shaped in a semi-circle form to find out the measurement of angles. To measure an angle using a protractor, follow the following steps:Step 1: Align the base of the angle with the base/origin of the protractor.Step 2: Using the lines on the protractor locate the angle (2nd line)Step 3: On each line on the protractor the degree will be provided. Find the angle and then read the degree.Step 4: Your finished! When reading the degree make sure that the reading is accurate. It MUST be read correctly. Even the answer is a degree off, the answer is incorrect.Method 2: Using facts and equations to determine your answer.Finding out the measurement of an angle using facts and equations will most probably be incorrect. That is why when you produce a answer measuring the degree of an angle, it is always in variants. (In other words: X-X degrees) For example; you are given a question like this:Question: What is the measure of the angle between the clock hands at 3:24? (On a 24 hour clock. Answer must be in variants)Answer: (Follow the Sections/Steps)Section 1: Establish the facts.Step 1: The hour hand on 24 hour clock rotates at 360 degrees every 12 hours. Or 30 degrees every hour or 1/2 a degree every minute.Step 2: The minute hand rotates 360 degrees every hour. Or 6 degrees per minute.That is all the facts required for this questionSection 2: Solving (Initial condition)Step 1: At 3 o' clock the angle is 90 degrees. The hour hand is at 3 and (assuming the 12 is 0) the minute hand is at 0.Step 2: In 24 minutes the hour hand moves (0.5 x 24)= 12 degrees. The minute hand will moves (6x24)= 144 degrees.Step 3: The new positions now are:Hour Hand: 90 + 12=102Minute Hand: 0 + 144=144Step 4: You can now determine the answer. Though, for this question there are 2 possible answers, depending on the way they are seen at. The two possible answers are:Answer 1: (144 - 102= 42) 42 degreesAnswer 2 :(360 - [144 - 102])= (360 - 42= 318)318 degrees.This formula is very logical and is a good concept to learn to instantly figure out an angle.Use a protractorWith a straight edged marked rule and a protractor.Use a protractor.Use a protractor.
How do you measure a reflex angel with 180 protractor?
To measure a reflex angle using a 180-degree protractor, first position the protractor so that its baseline aligns with one side of the angle, ensuring the center point is at the vertex. Measure the smaller angle formed on the protractor, which will be less than 180 degrees. Subtract this measurement from 360 degrees to find the reflex angle. For example, if the smaller angle measures 120 degrees, the reflex angle would be 360 - 120 = 240 degrees.
How can I accurately measure angles using a protractor?
To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
