If ΔABC and ΔPQR are to be congruent.

If ΔABC and ΔPQR are to be congruent, name one additional pair of corresponding parts. What criterion did you use?

Solution:

In the adjoining figure, ray AZ bisects ∠DAB as well as ∠DCB.
(i) State the three pairs of equal parts in triangles BAC and DAC.
(ii) Is ΔBAC = ΔDAC? Give reasons.
(iii) Is CD = CB? Give reasons.

Solution:

More Solutions:

• If ∠A = ∠B. Show that ΔAOC = ΔBOD.
• Fill in the blanks in Congruence of Triangles:
• Statements are true or false in congruence of triangles:
• Not a standard criterion of congruency of two triangles?
• If ∆ABC = ∆EFD, then the correct statement:
• Then ∆DEF = ∆PQR, by the congruence rule:
