300
Name 2 congruent angles and prove why.
Many answers!

What is the difference between CONGRUENT and SIMILAR?
Congruent is the exact same size.
Similar is the same shape, but a new size that is PROPORTIONAL to the original.

What is a proportional relationship? What are some key elements of a proportional relationship? What does it appear as on a graph, in an equation, or on a table?
A proportional relationship is a constant pattern comparing two things, such as cost per pound. Proportional relationships always make a straight line through (0,0) and have an equation like y=kx, where "k" is the pattern number. In a table, when you multiply X by the constant (k, the pattern) you get Y.

If there is one solution, what must be true about the slopes of the two lines?
Si existe una solución, ¿qué debe ser cierto acerca de las pendientes de las dos rectas?
The slopes have to be different (so that they intersect).
