any rays that intersect will form 4 angles
A single angle can only add up to its own value! And how can a single angle be congruent? There have to be at least two angles for them to be congruent (or not).
Any two angles who's measures add up to 180 degrees form a straight angle.
A supplemental angle "completes" a given angle to make it a straight angle (180 degrees). The supplement of 90 is 90. The supplement of 100 is 80. As long as the two angles add up to 180 they supplement each other. So, you have some angle, x and its supplement, 180-x. The supplement is twice as big as the angle. 180-x = 2*x Solve for x and you're done!
Complementary angles add up to 90*, so a 60* angle's complement is 30*.
20 degrees. the definition of a supplementary angle is two angles that add up to 180 degrees.
two rays make up an angle, so the rays are the sides of the angle.
No. If the rays do not meet, there is no angle.
It's true, an angle is made up of two rays. Two rays meet at a point, and their relative position at the point where they meet will define an angle.
A figure that is made up of two noncollinear rays with a common endpoint is an angle. The angle that is formed can be acute, right, obtuse or reflex.
um... it is pointy and looks like a house
an angle
angle
a right angle
An angle is a geometric figure formed by two rays that share a common endpoint.
It is an angle.
No. Two rays can be parallel and so would never form an angle. Also, an angle (a single one as opposed to a quartet of angles) is formed by two coterminus line segments. That is to say, the line segments stop where they meet. A ray goes on forever in both directions.
Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.
