what are the measures of angle a and angle b if angle a and angle b are complementary angles and angle a is equal to angle b

. If a ray rotates about the starting initial position, in anticlockwise direction, comes back to its original position after 1 complete revolution then it has rotated through 360 o . 1 complete rotation is divided into 360 equal parts. Each part is 1 o . Each part (1 o ) is divided into ..

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..

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

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 ..

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

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

Consider a block placed on a rough floor. Now, the reaction force is because it is equal and opposite to the weight . Now apply a horizontal force so that the block just begins to slide, i.e., the frictional force is equal to the limiting friction. When this condition i..

When two straight lines meet at a point they form an angle..

Fig.(i) Fig.(ii) Fig.(iii) Let OA and OB two half lines with common end point O. The half lines OA and OB are the sides of an angle and the point O is the vertex of the angle. An angle is an amount of rotation..
