## What is the sum of the exterior angles of a 4 sided polygon?

When the sides of a quadrilaterals are extended and the exterior angles are produced. The sum of four exterior angle is always 360 degrees.

## What is alternate in math?

The word ‘alternate’ is usually used with pairs of angles, to indicate that each is on opposite sides of a line. In the figure below, the two angles are called alternate angles because they are on opposite sides of the sloping transversal line.

## What is the formula for co interior angles?

The sum of the interior angles of a polygon of ‘n’ sides can be calculated using the formula 180(n-2)° Each interior angle of a regular polygon of ‘n’ sides can be calculated using the formula ((180(n-2))/n)°

## What is the Z angle rule?

Alternate angles form a ‘Z’ shape and are sometimes called ‘Z angles’. Any two angles that add up to 180 degrees are known as supplementary angles. Angle Sum of a Triangle. Using some of the above results, we can prove that the sum of the three angles inside any triangle always add up to 180 degrees.

## How do we name angles?

Angles are named in two ways. You can name a specific angle by using the vertex point, and a point on each of the angle’s rays. The name of the angle is simply the three letters representing those points, with the vertex point listed in the middle. You can also name angles by looking at their size.

## What are parts of angles?

Parts of Angles Vertex- The corner points of an angle is known as Vertex. It is the point where two rays meet. Arms– The two sides of angle, joined at a common endpoint. Initial Side – It is also known as the reference line.

## How do you name a 3 point angle?

When an angle is presented with three labeled points, the angle would be named using the angle symbol ∠ and the three points written with the vertex in the middle. The following angle could be correctly named ∠LMN or ∠NML, because in each case the vertex point is in the middle of the name.
