• all the angles of a triangle are less than 60°

In two triangles, ABC and PQR, ∠A = 30°, ∠B = 70°, ∠P = 70°, ∠Q = 80° and AB = RP, then

• ΔABC ≌ ΔPQR

• ΔABC ≌ ΔQRP

• ΔABC ≌ ΔRQP

• ΔABC ≌ ΔRPQ

In two triangles ABC and DEF, AB = DE, BC = DF and AC = EF, then

• ΔABC ≌ ΔDEF

• ΔABC ≌ Δ ΔEFD

• ΔABC ≌ ΔFDE

• none of these

If ΔABC is congruent to ΔDEF by SSS congruence rule, then:

• ∠C <∠F

• ∠B < ∠E

• ∠A < ∠D

• d) ∠A = ∠D, ∠B = ∠E, ∠C = ∠F

In the given figure, the congruency rule used in proving ∠ACD ≌ ∠ADB is

• ASA

• SAS

• AAS

• RHS

In the given figure, AD is the median then ∠BAD is

• 35

• 110

• 55

• 70

In a triangle PQR if ∠QPR = 80° and PQ = PR, then ∠R and ∠Q are

• 80°,70°

• 80°, 80°

• 70°, 80°

• 50°, 50°

In a triangle ABC, AB = 5 cm AC = 5 cm and angle A = 50 then angle B is equal to

• 35

• 65

• 80

• 40

Which of the following is a correct statement?

• Two triangles having same shape are congruent
