The angle $ECD$ is $360^\circ$. They are also responsible for mapping their results to provide for cities or architects. Hence, the two rays of the 180-degree angle are subtended towards the opposite direction, where the rays are joined to each other at endpoints. The measure of a reflex angle is added to an acute or obtuse angle to make a full 360 degree circle. An angle of $360^\circ$ is called a complete angle. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. The angle E C D is 360 ∘. In Maths, a straight angle is an angle equal to 180 degrees. Translations,rotation, reflection in real life! Basically, as per angles definition in maths, when two rays are joined end to end, they form an angle. The arms of a wall clock make acute angles at several hours of a day.

If you draw the diagonals of a square, a rhombus or a kite, the angle at the intersection is 90 degrees and is, therefore, a right angle. Info. A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. At an angle of 45°, we look both up and out, and this is a good paradigm for life.At 45° degrees, we can view both up: seeing and loving God, and out: seeing and loving our neighbor..
