A reflex angle is one that is more than 180 degrees but less than 360 degrees. If the reflex angle measured 190 degrees, then there would be a 170 degree, or obtuse, angle opposite it. If the reflex angle measured 270 degrees, then there would be a 90 degree, or right, angle opposite it. If the reflex angle measured 300 degrees, then there would be a 60 degree, or acute, angle opposite it. It helps to draw or picture these angles as sectors of a circle.

What is an straight and reflex angle?
A straight angle is an angle that measures exactly 180°A reflex angle is an angle that measures more than 180°, but measures less than 360°.Edit: I really like that answer that the controbuter did above ^. I just wanted to add something. A straight angle is an angle that is straight. A reflex angle would be an angle larger than a straight angle. It's an angle that's in the opposite side of a right angle or an acute.
How do you calculate a reflex angle using a protractor?
The other side of the reflex angle will be between 0 and 180 degrees. Measure that angle and subtract the answer from 360 degrees.
What is a 295 degree angle called?
reflex angle
Why is the sine of 90 degrees equal to 1?
Sine = Opposite divided by Hypotenuse Opposite is the side of the triangle opposite the angle (in this case the 90o angle). Hypotenuse is the side opposite the right angle in a right angle triangle. Therefore, Sine 90 = 1 because the opposite side and the hypotenuse are the same side, they are both opposite the right angle.
In a triangle the angle with the smallest measure is always opposite the?
shortest side
