3.5 Exterior Angle Theorem And Triangle Sum Theorem
The sum of each interior angle and exterior angle is equal to 180 straight line.
3.5 exterior angle theorem and triangle sum theorem. What is the Triangle Angle Sum Theorem. The sum of the interior measures of a triangle. In the figure above drag the orange dots on any vertex to reshape the triangle.
The most comprehensive learning site for K-13. 1 3 4 2. Apply the triangle sum theorem exterior angle theorem to solve for missing angle measures.
Find the value of x. Definition Remote interior angles. Exterior Angle Theorem The measure of an exterior angle in a triangle is the sum of the measures of the 2 remote interior angles exterior angle remote interior angles A C D Exterior Angle Theorem The measure of an exterior angle in a triangle is the sum of the measures of the 2 remote interior angles 3 2 1 4 exterior angle remote interior.
A very important consequence of the angle sum property of triangles is the exterior angle theorem which states that an exterior angle of a triangle is equal to the sum of its two interior opposite angles. So we all know that a triangle is a 3-sided figure with three interior angles. The two interior angles.

All of the problems are diagrams where students will solve for x or find a missing angle measure.
Worksheet 12 problems Agenda. One common property about triangles is that all three interior angles add up to 180 degrees. An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side.
