The interior angles of a regular polygon can be calculated using a formula. This formula allows us to calculate their sum based on the number of sides of the polygon. On the other hand, the sum of the exterior angles of any polygon is always equal to 360°. Therefore,...

The interior angles of a trapezoid always measure 360°. We have three main types of trapezoids: isosceles trapezoid, scalene trapezoid, and right trapezoid. Depending on the type of trapezoid, we can use a different method to find all the measures of its internal...

Heptagons have a sum of interior angles equal to 900°. In a regular heptagon, all the sides have the same length, so the interior angles also have the same measure. Therefore, each interior angle of a heptagon measures 120°. However, an irregular hexagon has different...

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°....

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...

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....
