Right

A right angle is 90 degrees.

it is called an obtuse angle - well im pretty sure

It is 1/2

sin(x) = cos(x)sin(x)/cos(x) = tan(x) = 1x = arctan(1) = 45 degreessin(45)=cos(45) = Sqrt(2)/2 Answer: By observation. Since Sine = Opposite over hypotenuse and Cosine = Adjacent over hypotenuse. Any right angle triangle where the opposite and adjacent sides are the same length will have Sine equal to Cosine. This only happens with an isosceles triangle (two sides are equal in length). When one angle is 90o the other two are 45o.

90 - 45 = 45 So another 45 degree angle is the complement of a 45 degree angle.

if you double a 45 degree angle you have a perfectly perpendicular angle, a 90 degree square corner.

it will become 45 degree

A 45-degree angle is an acute angle

A 45 degree turn is an angle

A 45 degree angle is its own complement; 45 + 45 = 90.
