Interior Angles of a Hexagon – Formula and Examples

Interior Angles of a Hexagon – Formula and Examples

Hexagons have a sum of interior angles of 720°. A regular hexagon has all its angles with the same measure, so each interior angle measures 120°. On the other hand, irregular hexagons have angles with different measures, but they always have a total sum equal to 720°....
Sum of Interior Angles of a Triangle

Sum of Interior Angles of a Triangle

The sum of interior angles of a triangle is always equal to 180°. This is because, if we join the three interior angles of the triangle, we will form a straight line. This property can be used to find the different measures of the three interior angles of the...
Exterior Angles of a Triangle – Formula and Examples

Exterior Angles of a Triangle – Formula and Examples

The exterior angles of a triangle are formed when we extend the sides of the triangle. The sum of exterior angles of a triangle is always equal to 360°. Therefore, depending on the type of triangle, we can apply different methods to find the measure of each angle....
Calculating Interior Angles of a Triangle

Calculating Interior Angles of a Triangle

The interior angles of any triangle have a total sum of 180°. Based on the lengths of their sides, we can distinguish three types of triangles: equilateral, isosceles, and scalene. Depending on the type of triangle we have, we can use different methods to calculate...
Interior Angles of a Polygon – Formula and Examples

Interior Angles of a Polygon – Formula and Examples

The sum of interior angles of any polygon can be calculated using a formula. The formula is derived considering that we can divide any polygon into triangles. If the polygon is regular, we can calculate the measure of one of its interior angles by dividing the total...
