69. mS 30; the base angles of an isosceles triangle are congruent. Since R is an obtuse angle, the unknown angles are the acute base angles of the triangle. The sum of the base angles is 180 120 60, so each base angle is equal to 30.

80. rectangle; using the Distance Formula, so the figure has opposite sides that are congruent. The slope of slope of 1 and slope of slope of

1, so the figure has two pairs of parallel sides, and consecutive sides are perpendicular. Therefore, the figure

is a rectangle.
