Step-by-step explanation:
Two bases first: that rules out cone and rectangular pyramid.
One lateral face: the only one with that is cylinder.

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.
The middle one would be the correct answer
you just need to substitute 3 in for x and solve each equation until both equations have y=-1
3x^2 + x - 3 - (x^2 - 5x + 1) =
3x^2 + x - 3 - x^2 + 5x - 1 =
2x^2 + 6x - 4 <===
