How is cosine defined?
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
What is angle of friction?
The angle of friction is defined as the angle of a plane where a body placed on the plane will start to slide.
Can a right angle equal 180 degrees?
No. A right angle is defined to be 90 degrees.
Does a right angle measure up to 90 degrees?
Yes a right angle is defined as an angle that measures exactly 900
Which geometric object is defined as the set of all points that are equidistant from the two sides of an angle?
The bisector of that angle.
How is cosine defined?
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
When is secant not defined?
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
What is angle of friction?
The angle of friction is defined as the angle of a plane where a body placed on the plane will start to slide.
Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
Definition of an acute angle?
An acute angle is defined as one that is less than 900.
Can a right angle equal 180 degrees?
No. A right angle is defined to be 90 degrees.
Does a right angle measure up to 90 degrees?
Yes a right angle is defined as an angle that measures exactly 900
Which geometric object is defined as the set of all points in a plane that are equidistant from the two sides of a given angle?
Bisector of an angle, is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.
Can there be a hypotenuse of a circle?
No. A hypotenuse is defined as the side opposite the right angle in a triangle that contains a right angle.
Which geometric object is defined as the set of all points that are equidistant from the two sides of an angle?
The bisector of that angle.
Is a strait angle obtuse?
An angle, x, is defined as obtuse iff 90°<x<180° Therefore a 'straight' angle (180°) is not obtuse.
What is the highest degree of a right angle?
A right angle is defined as 90 degrees, no more or less. If it's not 90 degrees, then it's not a right angle.
