The box and whisker plot below represents the grades in a college statistics course. Which interval contains exactly 50% of the grades? which do I circle:

O: 63-88
O: 63-95
O: 75-81
O: 75-88

Which is a true statement about an exterior angle of a triangle a. it is formed by two segments that are not sides of the triangle, b. it forms a linear pair with one of the interior angles of the triangle, c. it is complementary to one of the interior angles of the triangle. d. it is formed by two segments that are sides of the triangle.

State if the two triangles are congruent. if they are, state how you know?
