In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint. So how do we go about this? The remote interior angles are just the two angles that are inside the triangle and opposite from the to rephrase it, the angle 'outside the triangle' (exterior angle a) equals d + c (the sum of the remote.
Any of the four angles formed on the inside of two straight lines when crossed by a transversal.
Any of the four angles formed in the area between a pair of parallel lines when a third line cuts them. Like triangles, quadrilaterals have both interior and exterior angles. Every intersection of sides creates a vertex, and that vertex. The angles labeled 1, 2, 3, 4, and 5 in the note:
