Okay, for number seven, we need more than that.
00:08
We need to know, like, is this a triangle? what's going on? i need more.
00:12
So i need more info to help you.
00:15
I need a picture or something to help you with number seven.
00:21
Number eight, it says the area of a kite is 135.
00:29
The diagonal is nine.
00:32
So the area, to find the area of the kite, we do p times q divided by two.
00:49
All right.
00:50
So the area equals one diagonal times the other diagonal divided by two.
00:55
So 135 equals nine times q over two.
01:02
So i'm going to multiply times two on both sides.
01:08
So 135 times two is 270.
01:13
So, equals nine, two, because that's the other diagonal, divide by nine.
01:18
So the other diagonal is 30.
01:24
Trapezoid has a median, the mid -segment theorem.
01:42
Which of the following, because that's really, if it's your median, it's a mid -segment of both.
01:50
So it's going to be that.
01:52
Which of the following quadrilaterals has diagonals that do not bisect each other? well, all parallelograms bisect each other, and this is a parallelogram.
02:07
So is this one and this one.
02:09
So all three of these are parallelograms.
02:11
So it's a trapezoid.
02:13
Now, on a sassely, well, no, not even a sassilis.
02:16
So a trapezoid is right, because the other three are parallelograms, and parallelograms.
02:21
That's one of the characteristics of a parallelogram.
02:23
Which of the following conditions is not sufficient to prove a quadrilateral as a parallelogram.
02:27
Two pairs of sides are parallel.
02:31
That is.
02:32
Two angles are supplementary.
02:34
No.
02:35
Two diagonals bisect each other.
02:37
Yes...
