Angle relationship definitions please help

Hi there!

As you can see, 3 and 4 both are on one side of one line. They are created by another line intersecting that same line. Now, imagine if that line wasn't there. This would make it so 3 and 4, added together, made up that one side of the line.

The measure of one side of a line is 180 degrees. Add both sides of the line together, you get a full 360 degrees circle. Thus, this means 3 and 4 add up to 180 degrees.

The definition of supplementary angles is they are a pair of angles which add up to 180 degrees. (Complementary is add up to 90, I find this easy to remember by remembering c comes earlier in the alphabet, and 90 comes earlier than 180).

Therefore, your answer is angle 3 and 4 are supplementary angles.

Hope this helps!

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
