An angle is formed by two rays with a common endpoint.
angle
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
An angle is formed between the two rays at the common end point.
angle
An angle is a figure made up of two noncollinear rays with a common endpoint. The common endpoint is called the vertex, while the two noncollinear rays are called the sides of the angle.
An angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle.
