How do you construct an angle of 105 degrees using compass?
Using only a compass you cannot do it - you will need a straight edge as well.Draw a straight line AB.From A, using the length AB draw an arc above AB.From B, using the length AB draw an arc to intersect the first arc at C.Join CA.Then angle CAB is 60%From A, draw an arc to cut the two arm of the angle, AB and AC at X and Y respectively.From X, draw an arc between the two arms of angle CAB.Using the same length, repeat from Y so as to cut the previous arc at D.Join DA.DA bisects angle CAB and so angle DAB = 30 degrees.Now bisect angle DAB to give angle EAB = 15 degrees.At A, draw a perpendicular (facing downwards). If F is any point on the perpendicular, the angle EAF = 15 + 90 = 105 degrees.
What is the name of the angle formed by the intersection of two noncollinear rays AB and AC?

How many ways to name an angle?
There are three ways to name an angle, provided there are only three points on the angle. Say the vertex is point A, and there are two rays extending. Each has another point on it, points B and C. You can name this angle BAC, CAB, or A.
How do you construct 150 degree angle using compasses?
You also need a straight edge.Because of the poor graphic facility of this browser, the description is rather longer and sounds more complicated than it is.In summary, youdraw a 60 degree angle,bisect it, and thenconsider its supplement.So here goes (it will be easier if you read and do it together).:Draw a straight line.Mark a point A on the line.With the compasses, draw a quarter circle arc that intersects the line at point B.Using the same compass setting, draw another large arc from B which intersects the first arc at point C (angle CAB will be 60 degrees).With the compass point now at C, and still using the same compass setting, draw another arc to intersect the last arc at D.Angle DAB is 30 degrees.If BA is extended (on the other side of A) to a point E, the angle DAE is 150 degrees.You also need a straight edge.

How do you draw a 105 degrees angle?
Draw a line segment AB. Put your compass point at B and stretch the compass out until it is at point A. Now draw a circle. Now move the compass point to B, leaving the compass opening the same as before and draw another circle. The circles will intersect in two points. Call them C and D. Draw CD and name its intersection with AB as the point E. angle CEB is a right angle. Now you need to bisect the 90 degree angle you just constructed to get two 45 degree angles. Look in your book as to how to bisect an angle. The angle CAB = 60 degrees. So bisect it to get a 30 degree angle and then bisect it to get a 15 degree angle. You can get a 105 degree angle by adding the 90 degree angle and the 15 degree angle. Similarly, you can get a 75 degree angle by subtracting the 15 degree angle from 90 degrees. Look in your book on how to copy an angle.

How to draw 174 and name type of angle?
To draw an angle of 174 degrees, you can follow these steps: Draw a straight line using a ruler or straightedge. This will be one side of the angle. At one end of the line, use a compass to draw an arc of 174 degrees, making sure that the arc intersects the line you drew in step 1. Without changing the width of the compass, place the point of the compass at the other end of the line you drew in step 1, and draw another arc that intersects the first arc you drew in step 2. Draw a line connecting the endpoint of the line and the intersection point of the two arcs, creating the second side of the angle. Label the vertex of the angle with a capital letter. To name the angle, you can use the vertex letter and the endpoint letters, in that order, with the vertex letter in the middle. In this case, the angle could be named "angle BAC" or "angle CAB", depending on which endpoint you choose to name first. As for the type of angle, an angle of 174 degrees is an obtuse angle because it measures greater than 90 degrees but less than 180 degrees.
Which part of the angle is the vertex?
It is the angle opposite the given side of a figure (<CAB has Vertex of A because it is the tip of the moutain, which is the highest point)

Prove that the bisectors of 2 adjacent supplementary angles include a right angle?
∠DAB + ∠EBA = 180� ⇒ 2∠CAB + 2∠CBA = 180� (Using (1) and (2)) ⇒ ∠CAB + ∠CBA = 90� In ∆ABC, ∠CAB + ∠CBA + ∠ABC = 180� (Angle sum property) ⇒ 90� + ∠ABC = 180� ⇒ ∠ABC = 180� - 90� = 90� Thus, the bisectors of two adjacent supplementary angles include a right angle.
How do you full cab on a skateboard?
a half-cab is when your foot is in the middle of the board and move 180 degrees, there is no such thing as full-cabs, just 360's
