Equilateral: "equal"-lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and we have two legs, right? Also iSOSceles has two equal "Sides" joined by an "Odd" side. Scalene: means "uneven" or "odd", so no equal sides.
The equation that represents a proportional relationship is:
y = 32x
Because:
y/x = 32
So that implies that y is directly proportional to x.
Note that other equations represent a proportional relationship in some form, only that the relationship y = 32x is the only direct proportional relationship.
There's no pic or worksheet!!
The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points. So you can pick either or.
