60 degree angle is an acute angle in geometry and is expressed as π/3 in radians. We can construct a 60 degree angle using a compass, protractor, and a ruler.
A Right-Angled Triangle is a closed figure having three sides, three Angles and three edges such that one of the three Angles of a Triangle is of 90 degree. To find thevalueof tan 60 degrees, let us take one of the Angles 60 degrees. Hypotenuse:The longest side of all the three side...
Sine or sin In a right-angled triangle, one angle is 90°, and the other two when added together equal to the third angle. The most important and prominent angles are 0, 30°, 45°, 60°, and 90°. Sine is defined as the ratio of the perpendicular to the hypotenuse of a right-a...
