A trapezium has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
Quadrant angles are the angle lies in different quadrants. The angles which lie between 0° and 90° are said to lie in the first quadrant. The angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant and angles between 270° and 360° are in the fourth quadrant Quadrant angles are the angle lies in different quadrants.

Acute angles (less than 90 degrees) Obtuse angles (greater than 90 degrees) Right angles ( equal to 90 degrees)
If triangle has one obtuse angle other two angles are acute. Since, sum of angles of triangle is 180.
Coterminal angles are angles that are formed at the same vertex.
Any angle can be coterminal.
Coterminal Angles are two angles in standard position with the same terminal side.
Coterminal angles.
-330ô
Any angles can be coterminal. 10 and 370 - IF MEASURED IN DEGREES - are effectively identical.
The two angles that are coterminal with 206 degrees are 12 degrees and 30 degrees.
195 degrees.
the coterminal side of 45 degree is -315 degree
pi/2 is one possible answer.
An angle that is coterminal with 30 degrees can be found by adding or subtracting multiples of 360 degrees. In this case, an angle coterminal with 30 degrees could be 390 degrees (30 + 360) or -330 degrees (30 - 360). Coterminal angles have the same initial and terminal sides, but may differ in number of rotations around the unit circle.
