It could be, but not necessarily. If one ray is parallel to the ground, the other ray could be going straight up, or it could be parallel to the ground also, just going in a different direction. Think of an L. The angle in that L is 90 degrees. You could rotate that L in any direction so that it sticks straight up, or you could rotate it so that it is flat to the ground, or so that it is pointing down. It is still 90 degrees.

What 2 angles are in a kite frame?
There is a right angle (90 degrees) and a straight angle (180 degrees).
There are 90 degrees in a right angle how many degrees in a straight line?
There are no degrees in a straight line.The angle between two line segments that looks like a single straight line if you didn't knowwhere the vertex of the angle is, measures 180 degrees, and is called a "straight angle".
Adjacent angles add up to be 90 degrees?
No. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.
What shape has angles that add up to 360 degrees?
Square 90.______90. |. | |. | 90.______ 90.
What is An angle is four times its complement find its measure?
Complementary angles add up to 90 degrees and so 4 times 22.5 degrees = 90 degrees or if you mean 4 times 90 degrees then it is a full turn of 360 degrees
How many degrees in a straight angle?
180 Degrees ;]
Why is there 90 degrees in a right angle?
Because 90 degrees is half of a straight line. A straight line is equal to 180 degrees. 180 divided by 2 = 90.
How much degrees is a straight angle?
90 Degrees
An angle of 180 degree is called what?
a flat line.90 degrees is a straight corner, L180 degrees is a straight line, l270 degrees is a straight corner but opposite of 90 degrees, L360 degrees is a straight line that have turned all the way round, l
Which type of angle has the smallest numbers of degrees acute obtuse right or straight?
An acute angle. Acute is less than 90 degrees Right is 90 degrees Obtuse is greater than 90 degrees Straight is 180 degrees
Why the projectiles thrown with angle 30 degree and 90 degree have the same range?
No. The range of the projectile thrown at 90 degrees is 0. It goes straight up and then straight down!
Why is a right angle not 45 degrees?
Because then it would not be a right angle. A right angle is 90 degrees. It is straight up and to the right.
Do right angle have to be straight to be a right angle?
It has to be 90 degrees and yes, straight.
What angle that makes a straight line?
90 degrees
Why is it harder to move an object up a hill at 90 degrees than at 20 degrees?
While, if the hill is 90 degrees, then it is a cliff. That is to say, that you are not receiving any "help" from the 90 degree hill. You are just lifting the object straight up. Whereas the 20 degree hill provides a ramp.
Why does x equal 0 when finding the sin of 90 degrees?
On the unit circle sin(90) degrees is at Y = 1 and as that is on the Y axis X will equal = 0. Ask yourself. Where would 90 degrees be on a 360 degree circle? Straight up.
What is half of a straight angle called?
A straight angle is 180 degrees so half of that is 90 degrees of a right angle.
