Will give brainliest, and and stars, only to those who answer appropriately.

Here is a bit of math and the answers for you.

Step-by-step explanation:

Looking at the triangle, we can see that (2,7) and (7,2) are opposite points, just like 1/3 or 3/1 is. So, they are both ending in the same area, meaning that 2 opposites coming together to a common point will make it an,

For the second question, the definition of a parallelogram is a quadrilateral with two pairs of parallel sides. So, looking at our problem, you can see from M to A will be 2 up and 6 right. Then, H to T is going to be 2 up and 6 right again. Both M to H and A to T are equal also, meaning that MH=AT and MA=HT.

So, you have 2 pairs of parallel sides, meaning, it is a parallelogram.

solution

Q.1.

given A=(8,8)

B=(2,7)

C=(7,2)

now

AB=√{(8-2)²+(8-7)²}=√37

BC=√{(7-2)²+(2-7)²}=5√2

AC=√{(8-7)²+(8-2)²}=√37

since AB=AC≠BC

so it is an isosceles triangle.

Q.2.

A=(7,8)

T=(7,3)

M=(1,6)

H=(1,1)

now

AT=√{(7-7)²+(8-3)²}=5

MH=√{(1-1)²+(6-1)²}=5

AM=√{(7-1)²+(8-6)²}=2√10

HT=√{(7-1)²+(3-1)²}=2√10

sinceAT=MH

AND

AM=HT

SO,ATHM is a parallelogram.proved.

your answer is -9
