What is an exterior angle?

An exterior angle of a polygon is the angle formed between one side of the polygon and an extension of an adjacent side. This angle is located outside the polygon and is supplementary to the interior angle at that vertex.

How is an exterior angle formed?

An exterior angle is formed when one side of a triangle is extended to intersect with the other side outside of the triangle. This creates an angle that is exterior to the triangle and is supplementary to the adjacent interior angle.

Can an exterior angle be greater than 360 degrees?

No, an exterior angle cannot be greater than 360 degrees as it is measured from one side of a triangle to a line that extends the other side of the triangle, forming a straight line with the adjacent interior angle. Since a full circle measures 360 degrees, an exterior angle cannot exceed this value.

How is an exterior angle different from an interior angle?

An exterior angle is formed when a side of a polygon is extended, while an interior angle is formed inside the polygon where the sides meet. Exterior angles are supplementary to the interior angles of a polygon, meaning that they add up to 180 degrees. Interior angles are the angles formed inside a polygon when its sides intersect, and the sum of all interior angles in a polygon is determined by the number of sides it has.

What is the relationship between an exterior angle and its adjacent interior angles?

The relationship between an exterior angle and its adjacent interior angles is that the exterior angle is equal to the sum of the two adjacent interior angles. This property is known as the Exterior Angle Theorem and is true for any polygon, making it a fundamental concept in geometry.

Can two exterior angles be adjacent to each other?

No, two exterior angles cannot be adjacent to each other because exterior angles are formed by extending one side of a polygon, and thus they are never next to each other. Adjacent angles are those that share a common vertex and side, which is not the case for exterior angles.

How can you determine the measure of an exterior angle?

To determine the measure of an exterior angle, you can use the formula: Exterior Angle = 180° - Interior Angle. This means that the exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle. By finding the interior angles of the shape and then applying this formula, you can easily calculate the measure of the exterior angle.

What is the sum of the measures of all exterior angles of a polygon?

The sum of the measures of all exterior angles of any polygon is always 360 degrees.

Can a regular polygon have different measures for its exterior angles?

No, a regular polygon by definition has all its exterior angles equal in measure. Each exterior angle of a regular polygon is formed by extending one side of the polygon and an adjacent side, creating a consistent angle measurement throughout the polygon.

How can exterior angles be used to find missing angles in a figure?

Exterior angles in a figure can be used to find missing angles by recognizing that the exterior angle at a vertex is equal to the sum of the two remote interior angles. By knowing the value of the exterior angle and one of the interior angles at the vertex, you can solve for the missing angle by setting up an equation based on the relationship between exterior and interior angles. This method allows for calculating missing angles in a figure using the properties of exterior angles.
