How do you interpret first and third angle drawings?
First angle is interpretted by the drawing being positioned to the right of the section and third angle is interpretted by the elevation being positioned to the left of the section.
How do you draw an angle of 55 degree with compass and pencil?
you will have to construct a 135 degree angle first...but constructing a 90 degree with a 45 degree to give u the 135 degree angle and then using that as a reference, u will have to draw a 60 degree angle going counter clockwise from the 135 degree angle so that 135-60=55 degree...hahah I know it is confusing but if only i could show you...cz i mean visual is better than oral right !??! haha ^D^... hope i can help....
What will the measure of the second acute angle be if the first is 28?
If its a right angle triangle then the second acute angle is 62 degrees
The sum of the first two angles of a triangle are twice the measure of the third angle The first angle is half of the second angle What are the three angles?
The angles are 40, 80 and 60 degrees.
Emily is a geometry teacher. She asks each student to bring in a cutout of a parallelogram. She tells them that one angle must measure 50 and Acirc and deg and the length of one side must be 10 centim?
To create a parallelogram with one angle measuring 50 degrees, students can start by drawing a line segment of 10 centimeters. Then, they can construct a 50-degree angle at one end of the segment using a protractor. Next, they can draw another line segment of 10 centimeters starting from the endpoint of the first segment to form a parallelogram. The opposite angle to the 50-degree angle will also measure 50 degrees in a parallelogram.
What is identified as the first step to drawing a angle with a protractor?
The first step is probably to get a piece of paper.
When your drawing an angle with a protractor after you've drawn the first side of the angle your next step is to do what?
say it is a 90 degree angle; find the 90 degree line on the protractor and draw a line continuing from it about 1/2 a centimetre. Remove the protractor and join up the lines
How do you find the first angle and the second angle of a triangle?
use a protractor
What do you do if you don't have a protractor and you need it?
If you don't have a protractor, you can use a ruler and a compass to construct angles. First, draw a straight line and mark a point on it as the vertex of the angle. Then, use the compass to measure the desired angle by drawing arcs and creating intersections that you can connect to form the angle. Alternatively, you can use a piece of paper folded to create right angles or reference angles like 30, 45, or 60 degrees.
What are the steps to use to measure an angle using a protractor?
To measure an acute or obtuse angle:Put the cross-hairs at the centre of the base line of the protractor on the point of the angle;Align one zero on one arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor over the other arm;Read off the angle of the other arm with the scale that starts at 0o on the first arm.To measure a reflex angle:Measure the angle (of the small angle) between the arms as above;Subtract the found angle from 360o.Note:The base line of the protractor is the straight line marked on the protractor that runs from 0o to 180o; half way along this line will be a perpendicular line towards the 90o mark which may touch or cross the base line - this point is the "cross-hairs".To draw a given angle:To draw an acute or obtuse angle:Draw one arm of the angle;Put the cross-hairs at the centre of the base line of the protractor on the end of the arm that forms the point of the angle;Align one zero on the drawn arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor where the other arm should go;Mark the angle of the other arm with the scale that starts at 0o on the first arm.Draw in the other arm;Optional: mark the angle (between the lines) with a small arc near the point.To draw a reflex angle:Subtract the angle from 360oDraw as above; except the angle is marked with a small arc round the outside of the arms (instead of between them).
How do you know which set of numbers on a protractor you are suppose to use when measuring angles on a circle graph?
Assuming you've got a 180o protractor (and not a 360o angle measurer).To measure an acute, right or obtuse angle (ie 0o to 180o):Place the centre mark of the protractor on the centre of the angle (ie where the arms of the angle meet)Put one of the base lines (which will be marked 0o and 180o) on one of the arms of the angle, so that the other line of the angle is within the scale of the protractor.Use the scale which starts with 0o on the first arm to read off the angle to the other arm.To measure a reflex angle (ie 180o to 360o):Place the protractor centre as abovePut the base line as aboveUse the scale which starts with 180o on the first arm to read off the angle to the other arm.Add 180o to the angle found in step 3.
What are the 2 types of oblique drawing?
first angle projection and third angle projection.
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.
What is first angle projection in engineering drawing in detail?
in it object is placed in first quadrent
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.
A protractor has two scales how so you decide which scale to use to measure an angle?
place the centre of the protractor on the vertex Y of angle XYZ. Let the reference line of the protractor coincide with ray YZ of the angle. Find the 'zero' mark on the reference line of the protractor that coincides with ray YZ. Observe the markings that increase serially from the 0 that is near point Z.
How do you interpret first and third angle drawings?
First angle is interpretted by the drawing being positioned to the right of the section and third angle is interpretted by the elevation being positioned to the left of the section.
