America was first introduced to the Trump brand, however, by Donaldâs father, Fred C. Trump, who named his real estate company and supermarket chains âTrumpâ and drove a navy blue Cadillac with âFCTâ license plates.
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle. Under this definition, two angles are congruent provided either can be made to coincide (the vertex and the sides) with the other by a rigid motion.
Definition: When the rays are the two halves of a line (they point in opposite directions), the angle is called a straight angle: A straight angle measures 180o. Definition: When the sides of an angle are perpendicular, the angle is called a right angle: A right angle measures 90o.
