How do you draw a reflex angle that measures 245 degrees?
If you have a 360o protractor, you draw one side of the angle, measure 245o round from this line and then draw in the other side of the angle, and then mark a small arc around the reflex angle. If you only have a 180o protractor, you start again by drawing one side of the angle; then you measure 360o - 245o = 115o the "wrong way" round from this line to give the 245o the right way and draw in the other side, and then mark a small arc around the reflex angle.
What are the steps used to construct a triangle orthocenter?
Take the triangle and label the vertices ABC so that BC is the shortest side.Take your pairs of compasses and set them to the length BC.With the compass point on B draw a small arc to intersect AB and label this point DWith the compass point on C draw a small arc to intersect AC and label this point ENow construct the angle bisectors of BCD and CBE - where these two lines meet is the orthocentre:To construct an angle bisector:Set your compasses at some length.Mark a small arc on each arm of the angle; label the two points X and YWith your compasses set to any length greater than half XY, on one point (say X) draw a small arc between the arms of the angle approximately in the middle - this will be the other side of the point to the vertexWith your compasses on the other point (say Y) draw a small arc to intersect the arc drawn in the last step.Draw in the line between the two vertex and the intersection of the arcs - this is the angle bisector.Note:In constructing the angle bisectors, the first two steps are done in creating points D and E; the points X and Y are:for angle BCD: B and D as you are bisecting the angle at vertex Cfor angle CBE: C and E as you are bisecting the angle at vertex BYou can use your compasses set to the length BC for all the arcs to be drawn.As you have used the length BC to create the points D and E, the triangles created by BCD and CBE are isosceles - in BCD the equal side are BC and BD, in CBE the equal sides are CB and CE. Thus when you draw in the angle bisectors of BCD and CBE they are perpendicular to the base of their respective triangles and thus the heights of those triangles, which is also the height of the original triangle (as point A is on an extension of BD and CE respectively).If there is no one shortest side, either (or both) of points D and/or E will coincide with point A.
Why the diverging angle is smaller than converging angle for a venturimeter?
If the angle is greater than that, the pressure increases too quickly and the adverse pressure gradient will cause flow separation along the walls. By keeping the angle small, the flow remains attached and behaves nicely.
An angle whose measure is greater than 90 degree?
is called an obtuse angle. remembering trick: obtuse= large (more than 90 degrees) acute= cute/small (less than 90 degrees)

What is the small box at the vertex called?
I believe that it's not called anything, it is just a symbol to indicate that the angle is a right angle (90 degrees)
How can you draw an angle of specified measure?
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
How do you draw a reflex angle?
When an angle is drawn a small arc is normally placed near the vertex between the arms to show the angle. A reflex angle is one greater than 180°, so draw the two arms as normal and then draw a small arc around the vertex of the angle "outside" the arms of the angle, ie around the angle which is greater than 180° If the problem is how to draw the reflex angle with a protractor that only goes up to 180°, then note that "360° - the reflex angle" gives an angle which is less than 180° and can be measure by the 180° protractor. Draw one arm of the angle, measure the calculated angle (eg if the reflex angle was 200°, 360° - 200° = 160°, so measure 160°), draw the other arm, and then draw an arc around the vertex "outside" the arms to show the reflex angle (in the example, the 200° angle).
How do you use a protractor to measure quadrilateral angles?
Line up the vertex, then if it is an acute angle use the small number, obtuse use the big number, next all you have to do is bring your finger up to where the angle line is and see what number, big or small it lines up with on the protractor!
How many angles does the letter M have?
There is three. if you look at M there is three corners that are small, therefore its a acute angle (angle that measures less than 90 degrees.)
Is a circle a 360 sided figure?
No, because if a circle has a set amount of sides, then it must have a certain amount of angles, reguiring the vertex of the angle to be farther from the center than say,the midpoint of its adjacent angle. This violates a criterion of a circle, because not all (no matter how small the difference is) radii are equidistant from the center.
When was Small Angle Shades created?
Small Angle Shades was created in 1758.

How can you indicate an angle is a right angle?
