Isosceles acute triangle.

Vertices ( A(1,2) ), ( B(4,6) ), ( C(7,2) ) Graph the quadrilateral with vertices A(-2, 2), B(1,

( DE = 5, EF = 4, DF = 4 ) → Isosceles, right triangle (since ( 3^2+4^2=5^2 ) actually? Wait, check: D to F: ( \sqrt(1+3)^2 + (1-1)^2 = 4 ) Yes, so sides 5,4,4 → Not right because 4²+4² ≠ 5². Acute isosceles.) Graph the quadrilateral with vertices A(-2
