Which expression is equivalent to

Can you draw an isosceles triangle with only one 80 degree angle?

An angle that measures between 90 and 180° is called a(,

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
