00:0-1 | Mhm . Hello , friends . Welcome to new Happy | |
00:08 | Learning video . Look at these images . Do you | |
00:14 | know what we're looking at exactly ? They are angles | |
00:23 | , and today we are going to learn many things | |
00:26 | about them . An angle is space between two intersecting | |
00:32 | lines or surfaces that emerged from the same point called | |
00:37 | Vertex . If you look around , we are surrounded | |
00:44 | by angles like the ones this clock handles or an | |
00:53 | ice cream cone makes . The unit of measure of | |
00:59 | the angles is the degree , and the most important | |
01:04 | angle of all is this one . It's called a | |
01:07 | right angle , and it measures 90 degrees . The | |
01:12 | tiny zero you can see in the right upper part | |
01:16 | of the number 90 is a symbol that represents all | |
01:20 | angles . We say that a right angle is the | |
01:25 | most important one because it is the one that is | |
01:29 | used to compare all of the other angles . The | |
01:33 | angles that a smaller than of right angle are called | |
01:36 | acute angles , and they measure less than 90 degrees | |
01:41 | . Like all of these , and the angles that | |
01:45 | are bigger than a right angle are called obtuse angles | |
01:50 | and measure more than 90 degrees . Like all of | |
01:53 | these to know the degrees at an angle measures . | |
01:59 | We need to use this instrument , which is called | |
02:03 | a protractor , So we need to place the straight | |
02:09 | part of the protractor over one of the sides of | |
02:12 | the angle , making the Vertex and the central point | |
02:15 | of the protractor meet . After this , we need | |
02:20 | to look at the tractor line on the other side | |
02:23 | of the angle and look at what number it says | |
02:26 | . These are the degrees . That's an angle . | |
02:28 | Measures easy peasy , huh ? Let's practice . We | |
02:34 | said that the right angle is 90 degrees . Let's | |
02:41 | see . We'll get the protractor . And indeed a | |
02:46 | right angle is 90 degrees . We haven't fooled you | |
02:50 | . Her . Oh , now let's measure this angle | |
02:56 | . Let's see how much it measures 45 degrees . | |
03:01 | It's an acute angle because it is smaller than a | |
03:04 | right angle . And now we're going to check out | |
03:08 | how much this other angle measures 120 degrees , of | |
03:14 | course . Mm . It's an obtuse angle because it | |
03:19 | measures more than 90 degrees . Imagine that Instead of | |
03:24 | being 120 it measures 180 . Do you know what | |
03:29 | this angle is called ? We call it a straight | |
03:33 | angle . Hey , and what about if it measures | |
03:40 | 360 degrees ? Well , that's a complete or full | |
03:46 | angle . It's complete , as can be a circumference | |
03:52 | measures 360 degrees . What a discovery . Measuring angles | |
03:59 | is easy peasy and fun , don't you think ? | |
04:04 | Goodbye , friends . And don't forget to subscribe to | |
04:07 | Happy learning TV Mhm . |
