congrent triangles

∠Two triangles ABC & PQR are congruent, If m<ABC = 50°, then m<PQR= _______.  

• 30°
• 50°
• 70°
• 90°

Let ABC and PQR are two triangles such that  ΔABC≅ΔPQR, at  ΔABC≅ΔPQR,

• ΔABC is congruent to ΔPQR, meaning corresponding sides and angles are equal.
• ΔABC and ΔPQR have different angles, but the same side lengths.
• ΔABC has a larger area than ΔPQR, but they are not congruent.
• ΔABC is similar to ΔPQR, meaning corresponding sides are proportional.

Let ABC and PQR are two triangles such that  ΔABC≅ΔPQR, If  Δ ABC≅Δ XYZ,

Then ΔPQR is ....... to ΔXYZ

• similar
• equal

Let DEF and GHI be two triangles such that  ΔDEF≅ΔGHI, at  ΔDEF≅ΔGHI,

• ΔDEF is congruent to ΔGHI, meaning corresponding sides and angles are equal.

• ΔDEF and ΔGHI have different angles, but the same side lengths.

• ΔDEF has a larger area than ΔGHI, but they are not congruent.

• ΔDEF is similar to ΔGHI, meaning corresponding sides are proportional.
