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
When was the protractor invented?
1801 was the year the first advanced protractor was invented by Joseph Huddard
How do you draw a quadrilateral with one reflex angle?
Draw the first two sides of any rectangle. Then from the free ends draw two lines which meet quite close the the corner you have drawn.
How do you draw a right obtuse triangle?
Triangles are either accute, obtuse, or right. To draw an accute triangle start by drawing an accute angle (less than 90 degrees). Then extend the ends of the angle and connect them making sure that both new angles are also acute. To draw a right triange first draw a right angle. Then extend the angle and connect to form two accute angles. To draw an obtuse triangle first draw an obtuse angle (greater than 90 degrees). Then extend the sides of the angle and connect creating 2 accute angles.
There are 7 balls in a box 3 black and 4 red a ball will be drawn and not replacecd then a second ball wil lbe drawn what is the chances it will be a black ball and then red ball?
The probability of getting on the first draw a black ball is: P(B1) = 3/7. The probability of getting a red ball given the event of drawing a black ball on the first draw is: P(R2│B1) = 4/6. The probability of drawing a black ball on the first draw and a red ball on the second draw is: P(B1UR2) = P(B1)∙P(R 2│B1) = (3/7)∙(4/6) = 0.2857... ~ 0.286 ~ ~ 28.6%
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.

What is auto-graphic projection in tachnical drawing?
In first angle auto graphic projection the planed, view is drawn exactly below the front elevation. What is viewed from the left is drawn from the right side of the front, it is drawn in the 1st angle and 3rd angle.

What are the steps to use to measure an angle using a protractor?
Place the center of the protractor on the vertex of the angle. Align the base of the protractor with one side of the angle. Read the measure where the other side of the angle intersects with the protractor scale. Note the measure in degrees.
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 are the 2 types of oblique drawing?
first angle projection and third angle projection.
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 is first angle projection in engineering drawing in detail?
in it object is placed in first quadrent
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 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.
