Students will I. Classify triangles using side measures - classify as equilateral, isoscles, or scalene angle measures - classify as acute, right, or obtuseII Find the missing angle in a triangle (solve for x), and then use angles to classify the triangle as acute, right, or obtuse. II Solve =for angle "x" to determine whether a triangle is isosceles or equilateral
