Parallel Lines and Triangles Chapter 3.5 Parallel Lines and Triangles TARGET: Using relationships between interior and exterior angles in a triangle.

The interior is the set of all points inside the figure The interior is the set of all points inside the figure. The exterior is the set of all points outside the figure. Exterior Interior

An interior angle is formed by two sides of a triangle An interior angle is formed by two sides of a triangle. An exterior angle is formed by one side of the triangle and extension of an adjacent side. 4 is an exterior angle. Exterior Interior 3 is an interior angle.

Each exterior angle has two remote interior angles Each exterior angle has two remote interior angles. A remote interior angle is an interior angle that is not adjacent to the exterior angle. 4 is an exterior angle. The remote interior angles of 4 are 1 and 2. Exterior Interior 3 is an interior angle.
