Exterior angles Of A Triangle
An exterior edge of a triangle is created by any side ofa triangle and also the extension of its adjacent side.
The Exterior angle Theorem says thatAn exterior edge of a triangle is equal to the sum of the twoopposite interior angles.
Example:Find the values of x and also y in the following triangle.
Solution:x + 50° = 92° (sum of opposite inner angles = exterior angle)x = 92° – 50° = 42°y + 92° = 180° (interior angle + nearby exterior angle = 180°.)y = 180° – 92° = 88°
