- Q1Consider the two triangles shown. If triangle ABC is similar to triangle FED, what is the value of x?75°55°20°130°30s
- Q2Suppose ∠ACB≅∠AED in the figure shown. Based on the figure and the given statement, which can prove that △ACB∼△AED?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.30s
- Q3Are all right isosceles triangles similar? Explain.No! B/c we need to know all sides are proportionalYes! 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 SSS30s
