Exterior Angles Of A Triangle Video Lessons Examples Step By Step An exterior angle of a triangle is equal to the sum of the two opposite interior angles. example: find the values of x and y in the following triangle. solution: x 50° = 92° (sum of opposite interior angles = exterior angle) x = 92° – 50° = 42°. y 92° = 180° (interior angle adjacent exterior angle = 180°.) y = 180° – 92° = 88°. Using the exterior angle theorem to solve problems. example: find the values of x and y in the following triangle. solution: x 50° = 92° (sum of opposite interior angles = exterior angle) x = 92° – 50° = 42°. y 92° = 180° (interior angle adjacent exterior angle = 180°.) y = 180° – 92° = 88°.
Exterior Angles Of A Triangle Video Lessons Examples Step By Step Discover the exterior angles of a triangle with our full solution guide. get step by step solutions, watch video solutions, and practice with exercises to master the exterior angles of a triangle. An exterior angle must form a linear pair with an interior angle. this means that the exterior angle must be adjacent to an interior angle (right next to it they must share a side) and the interior and exterior angles form a straight line (180 degrees). if you extend one of the sides of the triangle, it will form an exterior angle. In this video, we will see how we can complete geometric proofs using the angle sum of a triangle and we’ll also find the interior and exterior angles of triangles. let’s start with the fact that the sum of the measures of the interior angles in any triangle is 180 degrees. of course, we’ve probably used this lots of times in mathematics. Exterior angle theorem. the exterior angle d of a triangle: equals the angles a plus b. is greater than angle a, and. is greater than angle b. example: the exterior angle is 35° 62° = 97°. and 97° > 35°. and 97° > 62°.

Are the exterior angles of a triangle always obtuse? no, the exterior angles of a triangle may not always be obtuse (more than 90°). however, the sum of all the three exterior angles should always be 360°. for example, if two exterior angles of a triangle are 165° (obtuse) and 141° (obtuse), the third one is 54° (acute). The above statement can be explained using the figure provided as: according to the exterior angle property of a triangle theorem, the sum of measures of ∠abc and ∠cab would be equal to the exterior angle ∠acd. general proof of this theorem is explained below: proof: consider a ∆abc as shown in fig. 2, such that the side bc of ∆abc is.
