Let's do this question.
Q Is a point in line PR given angle is Cutie's equal to 90 degrees right now.
There are two true or false statements of the video.
Give it a try and then let's do it together.
All right.
We're back.
I hope you've given it a try.
Let me mark these angles, this angle, one angle to an angle three.
Now, the first statement says Angle P.
Q s and angle are Kutty are complimentary.
What does Angle P.
Q s that's angle one over here.
And Arcudi, that's angle three over here.
Now what do we mean with complementary angles.
It means that when you add the two angles you should get ninety degree.
All right.
Now over here, one plus two plus three.
That is, if you add these three angles, you will get 180 degrees.
Right, because this bar is a straight line and we know that a straight angle is equal to 180 degrees.
All right.
Now, it's given that angle two is equal to 90 degrees.
Right.
Therefore, angle one plus angle three is equal to 180 minus 90, which is equal to 90 degrees.
Therefore, when you are adding them, you're getting ninety degrees and hence they are complementary.
And this statement is true.
What about the next statement, and I'll pick you as an angle, you are supplementary angle US is angle
one and angle s Q are is equal, angle two plus angle three.
Right now, supplementary means.
When you add them, you should be getting 180 degrees right now.
Angle one plus angle two plus angle three is equal to 180 degree because we are in a straight line.
So this is a straight angle therefore.
Yes, this is also true.
Right, because you're adding them and you're getting 180 degrees.
