  • Q2
    Suppose ∠ACB≅∠AED in the figure shown. Based on the figure and the given statement, which can prove that △ACB∼△AED?
    Question Image
    AC is proportional to AE, and since two corresponding angles are congruent, △ACB∼△AED.
    AB is proportional to AD, and since two corresponding angles are congruent, △ACB∼△AED.
    m∠ABC=m∠ADE=80°, and since the three corresponding angles are congruent, △ACB∼△AED.
    m∠ABC=m∠ADE=40°, and since the three corresponding angles are congruent, △ACB∼△AED.

  • Q3
    Are all right isosceles triangles similar? Explain.
    No! B/c we need to know all sides are proportional
    Yes! B/c the triangles will be congruent.
    Yes! B/c then the both triangles would have base angles of 45 and 45 (AA)
    Yes! B/c of SSS
