How do you construct angle of 142.5 degrees?
To construct an angle of 142.5 degrees, you can start by drawing a straight line using a ruler. Then, using a protractor, mark a point on the line to serve as the vertex of the angle. Next, align the protractor so that the 0-degree mark is at one end of the line and the 180-degree mark is at the other end. Finally, mark a point at 142.5 degrees on the protractor, and draw a ray from the vertex through that point to create the angle of 142.5 degrees.
How do you draw an angle with a protractor?
Figure out which way you want to draw your angle. If you wish to draw the angle to the left, use the bottom row of numbers listed on the top and sides of your protractor and vise versa. Make a mark next to the number of the angle you wish to make (example: a 45 degree angle you would make a mark next to the number 45) then trace the bottom flat edge of the protractor. Using the mark you just made, make a line to connect the mark and the line you drew.
How do you draw a perpendicular line which divide a line in to equal parts?
Use a ruler to measure the line (horizontal?) and mark the middle of the line, then use a right-angle triangle to draw a vertical line 90 degrees from the mark. Or you can use a compass fitted with a pencil to draw arcs that will give the middle mark and a mark to line a ruler against to draw the perpendicular line required. Search Google for using a compass.
How to draw 100 degree angle?
First, draw a line. Then, using a protractor, depending on what type of protractor you have, make a mark next to the 100° mark or 10° away from 90°. Finally, draw another line.
What is the line above a word in Spanish called?
the accent mark
Sine of a 50 degree angle?
50° angle measure 50° m?= 50° replace the question mark with the line's name, or what the line is called.
What do you call the mark above a short vowel?
The mark above a short vowel is called a breve. It is used to indicate that the vowel is pronounced as a short sound.
What is the punctuation mark for a short i?
The punctuation mark for a short "i" sound is a breve, which looks like a small curved line placed over the letter "i." It is used in certain linguistic contexts to indicate that the vowel is pronounced with a short sound.
What is the mark over a short vowel called?
The mark over a short vowel is called a breve. It is a diacritical mark used in various languages to indicate a short or light pronunciation of the vowel it is placed over.
What symbol do many dictionaries use to mark a short vowel sound?
Many dictionaries use the symbol (˘) called a breve to mark a short vowel sound.
Can you make a straight line into curved line?
yes you can so if you put two lines meeting at a 90' angle then put as many marks on the lines but make sure you put the same amount of marks on each of the line then number the mark on one line then the number number you started with goes at the end of the line you havent numbered the join the numbers up
What is a long thin mark called?
A long thin mark is called a "line."
Why is 180 sometimes called straight angle?
Because if there's no little dot to mark the vertex of a 180-degree angle, then you don't even know that you're looking at an angle, because it looks just like a straight line. To put it the other way, if somebody tells you to construct a 180-degree angle with nothing but a ruler, all you have to do is draw a straight line and mark a little dot anywhere on it, and boom, you've got a 180-degree angle with its vertex located at that dot.
How do you draw an angle with a protractor?
Figure out which way you want to draw your angle. If you wish to draw the angle to the left, use the bottom row of numbers listed on the top and sides of your protractor and vise versa. Make a mark next to the number of the angle you wish to make (example: a 45 degree angle you would make a mark next to the number 45) then trace the bottom flat edge of the protractor. Using the mark you just made, make a line to connect the mark and the line you drew.
What is the mark over a vowel indicating it is sounded separately?
A horizontal line This "horizontal line" that indicates a long vowel is called a Macron. The curved line(the "smile") over a short vowel is a Breve.
How do you draw angles greater than 180?
First, if the angle is 360° or more, find the remainder of the angle divided by 360 - this is as 360° represents a full turn. If you have a 360° protractor just measure off the angle. If you only have a 180° protractor, then there are two ways it can be done as the protractor is marked so that 0° - 180° can be measured from either end of the base line: Method 1: excess over 180° 1) Subtract 180° from the angle to get the excess over 180°. 2) Place the protractor on the line, centred on the vertex of the angle on the left of the line, with the top 0°/180° mark on the line. 3) Measure the excess over 180° calculated in step 1 from the bottom 0° mark of the protractor. 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. Method 2: acute/obtuse angle of the reflex angle to complete a full turn 1) Subtract the angle from 360° to get the angle which completes the full turn 2)Place the protractor on the line, centred on the angle vertex on the left of the line, with the top 0°/180° mark on the line. 3) Measure the angle to complete the full turn calculated in step 1 from the top 0° mark of the protractor (on the line). 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. The above assume a clockwise angle is being drawn from a vertical line with the angle vertex at the bottom. For anticlockwise angles, place the protractor on the right of the line. For a non-vertical line [mentally] rotate the paper so that the first arm of the angle is vertical with the angle vertex at the bottom.
