Let's do this question, ABCDs, a quadrilateral in which is equal to five centimeter and Krazy Glue
eight centimeter, the sum of the angle E and D is 180 degrees.
What is the name of this quadrilaterals?
All right.
This is a fundamental question.
It just helps you to solidify your base.
Now, pause the video, give it a thought, and then let's do it together.
All right.
Let's do it together.
We have ABCDE and it's given ABS equal to five centimeter and CDs equal to eight centimeters.
It's also given that angle, eight plus angle is equal to 180 degree.
Right.
So from this we can understand that abs parallel to D.C., right.
Because the consecutive indeed triangles are supplementary and we have seen that.
If that is true, then the two lines will be parallel.
Now, therefore, the answer to this question is tropism y because we have seen that AB is parallel
to city and the length is not equal.
So this is five.
This is longer.
This is eight.
So these two sides cannot be parallel.
Therefore, it's not a program.
Right.
And it's not a rhombus.
We'll see that.
A rhombus is also about kilogramme in a future video.
And hence this is a tropism.
The correct answer is option B.
All right.
Now, let's do the second question, but which of the following diagonals bisect each other?
So what's the correct answer?
We know that in the case of a parallelogram, the diagonals bisect each other.
Right.
Therefore, the correct answer is option E, because the square is also a program we have seen over
here that trapezius is not a program and inequality is also not a problem.
And in a future video, we will see that a kite is also not a program.
Therefore, the correct answer is option E, that is a square.
All right.
What about the next question?
Well, which of the following figures or angles are equal?
The correct answer to this will be.
Option eight, that is a rectangle, right, because each angle is equal to 90 degrees in the case of
a rectangle.
So option is the correct answer.
Over here, you can see in the case of a trapezius, every angle is not equal.
So that's not the answer.
Right and wrong.
But also you will see that all angles are not equal.
And same in the case of a kite, although you will see that all angles are not equal.
The only four sided polygons in which all angles are equal are rectangles and squares where each angle
is equal to 90 degrees.
