The measure of angle CXE is 60°.

“Angle between two vectors is the shortest angle at which any of the two vectors is rotated about the other vector such that both of the vectors have the same direction.”

Anti-parallel vectors are those parallel vectors that are opposite in direction. Angle between such two vector is 180°…

In geometry, an angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex. Angles are measured in degrees ( °), using a protractor.

Subtract the degrees of the acute angle from 360. The degrees of the reflex angle and the degrees of the smaller acute angle would add up to 360. To continue the example, if the smaller acute angle measures 26.565 degrees, the reflex angle would measure 333.435 degrees.

Here are the steps to construct 40 degree angle with compass and ruler:

1. Draw a straight line of any measurement with the help of ruler.
2. Take your compass and draw an arc of any measurement.
3. Draw 90 degree angle.
4. Now draw 60 and 120 degree angles.

Bisecting angles without a protractor

1. Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.
2. Place the compass on the point where one arc crosses an arm and draw an arc inside the angle.
3. Use a ruler to join the vertex to the point where the arcs intersect (D).

Using ruler and compasses , construct angle XYZ =angle AOB . Also , verify it by measurement.
