Good morning mathematicians all over the world.
I shall be bringing to the angles in a polygon.
Objective
- Identify, name and calculate angles meeting at a point and angles where a transversal crossess parallel lines.
Angles Between Lines
This section revises the property of angles (I) meeting at a point, (ii) at the points where a transversal parallel lines.
Number one.
The sum of the angles on a straight line is 180 degrees..
See the figure 1 below:
Number two
Vertically opposite angles is equal
Number three
Sum of angles at a point is 360 degrees
Number four
When transversal angles crosses parallel lines, corresponding angles are equal.
Lastly, when transversal angles crosses parallel lines, vertically opposite angles are equal.
Pictures while solving and constructing the lines and angles.
