An angle is a portion of the plane between two rays that are joined by a vertex.A straight angle is the shared space between two rays joined by a vertex measuring 180º.We can also think of an angle as the amplitude of a line’s rotation over a point. Therefore a straight angle ...
A straight angle pair is a pair of angles that form a straight line. The sum of two or more angles that are in this pair is always equal to 180°. We also call them linear pairs of angles. The image given above shows two angles ∠a = 125° and ∠b = 55°, which together for...
