The given quadrilateral is a kite.
Given: Point A (2, 4), B (-2, -5), C (7, -1) and D (7, 4)
Firstly, we find the distance between AD and DC
AD =
⇒ AD =
⇒ AD = 5
DC =
⇒ DC =
⇒ DC = 5
Hence, AD = DC = 5
Now, find the distance between AB and BC
AB =
⇒ AB =
⇒ AB =
⇒ AB =
BC =
⇒ BC =
⇒ BC =
⇒ BC =
Hence, AB = BC = √97
In the given quadrilateral, the two pair is of equal length and these sides are adjacent to each other.
Hence, it follows the property of kite.

<h3><u>Question:</u></h3>
Identify a3 of this sequence: 0.25, 0.5, 0.75, 1, 1.25, 1.5,...a3=
<h3><u>Answer:</u></h3>The third term of sequence is 0.75
Given that, sequence is:
0.25, 0.5, 0.75, 1, 1.25. 1.5
Let us find the difference between terms
This is a arithmetic sequence
Because the difference between any term and its immediately preceding term is always 0.25
In a arithmetic sequence,
Thus, in the sequence 0.25, 0.5, 0.75, 1, 1.25. 1.5
Thus the third term of sequence is 0.75
