How can you find exterior angles?
Exterior Angles of a Regular Polygon with n sides: Exterior angle = 360°/n. We will use the formula of the sum of interior angles and exterior angles to answer this question. Explanation: The sum of interior angles is given by 180 (n – 2), where n is the number of sides.
Can an exterior angle be complementary to an interior angle?
The exterior angle theorem states that: The measure of an exterior angle of a triangle is supplementary to its adjacent interior angle.
Are exterior angles supplementary?
The theorem states that same-side exterior angles are supplementary, meaning that they have a sum of 180 degrees.
How do you use the exterior angle theorem?
What is the Exterior Angle Theorem Formula? The sum of the exterior angle = the sum of two non-adjacent interior opposite angles. An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.
Which angle is an exterior angle?
The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. When we add up the Interior Angle and Exterior Angle we get a straight line 180°.
How do you find out if an angle is supplementary or complementary?
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. Note that in these definitions, it does not matter whether or not the angles are adjacent; only their measures matter.
How do you describe an exterior angle?
noun Geometry. an angle formed outside parallel lines by a third line that intersects them. an angle formed outside a polygon by one side and an extension of an adjacent side; the supplement of an interior angle of the polygon.
What are the properties of complementary angles?
The properties of complementary angles are given below. Two angles are said to be complementary if they add up to 90 degrees. Two complementary angles can be either adjacent or non-adjacent. Three or more angles cannot be complementary even if their sum is 90 degrees.
How do you find the exterior angles of a polygon?
An exterior angle can be found through the use of complementary angles. False The sum of the interior angles of all polygons with 5 or more sides is exactly the same.
What is the difference between adjacent and non adjacent complementary angles?
Adjacent Complementary Angles. Non-adjacent Complementary Angles. Adjacent Complementary Angles: Two complementary angles with a common vertex and a common arm are called adjacent complementary angles. In the figure given below, ∠COB and ∠AOB are adjacent angles as they have a common vertex “O” and a common arm “OB”.
What is the complementary angle of 40 degrees?
The complementary angle of 40 degrees is: 90 – 40 = 50 degrees How to find supplementary angles? To find the angle which is supplementary to another angle, subtract the given angle from 180 degrees.
