Right Angle Triangle of Trignometry

It has three sides and the total angle is 180 degree. In the right angled triangle the side opposite to 90 degrees is called the hypotenuse and the opposite side is the side that is just opposite to angle A (the angle which is to be found), the other side is the adjacent side,take a look on free trigonometry answers for your queries so the length of the side is taken as a,b,c here a is the side length of the opposite, b is the side length of the base that is adjacent and the c is the side length of the hypotenuse. Angle of the right angle triangle will be measured in terms sin, cos, tan (we know that the total angle is 180 degree for any triangle) sin A=a/c, cos A=b/c and tan A=a/b.
The reciprocals of sin functions named the cosec ,Do not worry when there is online trigonometry homework help.cos functions named sec and tan functions is named as cot and also the inverse functions of sin is called as arcsine ,cos is called arccosine and the tan function is called as arc tan respectively .
