angle a and angle b are complementary. angle a and angle c are supplementary. what shall be the minimum measure of angle a + angle b + angle c ?

Definition - When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m..

If the sum of the two angles is one right angle (i.e., 90 o ), they are called complementary angles..

Reflex Angle : An angle whose measure is more than 180 o and less than 360 o is called a reflex angle..

They are a pair of angles, the sum of whose measures is equal to 90 o . These may be adjacent angles as well. (These are adjacent angles) (These are not adjacent angles..

In a given plane two lines intersect at only one point. The angles are measured with the help of a protractor. The measure of an angle is called its magnitud..

Consider a body placed on a platform whose angle with the horizontal can be changed for e.g., a tipper with stones at the back. The weight W can be resolved into two rectangular components. W cos f and W sin f . The component W ..

Two angles are said to be supplementary, if the sum of their measures is 180 o..

They are a pair of angles, the sum of whose measures is equal to 180 o . These may be adjacent angles as well. [See figure below] [See figure below] (non-adjacent angles..

If two angles are complementary, then each angle is _________. => a right angle or an acute angle or an obtuse angle or a supplement angle..

Which of the following angles measures greater than a right angle? => ∠ c or ∠ b or ∠ d or ∠ a..
