Angles In A Triangle. A triangle is the simplest possible polygon. It is a two-dimensional (flat) shape with three straight sides forming an interior, closed space. It has three interior angles.One of the earliest concepts to learn in geometry is that triangles have interior angles adding up to 180 °.But how do you know? Angle Tasks 1: Parallel Lines and Transversals Framework Cluster Reasoning About Equations and Angles Standard(s) 8.G.5 Use informal arguments to analyze angle relationships Recognize the relationships between interior and exterior angles of a triangle Recognize the relationships between the angles created when Note: Got a diagram of a transversal intersecting parallel lines? Trying to figure out all the angle measurements? Take a look at this tutorial, and you'll see how find all the missing angle measurements by identifying vertical, corresponding, adjacent, and alternate exterior angles! When a transversal intersects two lines, we can compare the sets of angles on the two lines by looking at their positions. The angles that lie on the same side of the transversal and are in matching positions are called corresponding angles (corr.\(\angle\)s). In the figure, these are corresponding angles:
