Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.

<em>Additional comment</em>
It is impossible to specify an equilateral triangle using rational coordinates.
Answer:
1/3
Step-by-step explanation:
probability = favorable outcomes/total possible outcomes
There are two favorable outcomes, 2 and 5.
There are 6 total possible outcomes.
Make your fraction.

Answer:
She subtracted the two 10x's where instead you're supposed to add them together.
Step-by-step explanation:
Answer:
doesn't x equal 6 too?
Step-by-step explanation:
since x is the same size as the other side of the triangle
your marks 9 my marks 5
Step-by-step explanation:
1/2 of 14 = 7
7 + 2 = 9
14 - 9 = 5
so your marks are 9 and mine are 5
Hope this helped ..
