triangles

Which of the following is not a criterion for congruence of triangles?

• SAS

• ASA

• SSA

• SSS

If AB = QR, BC = PR and CA = PQ, then

• ∆ ABC ≅ ∆ PQR

• ∆ CBA ≅ ∆ PRQ

• ∆ BAC ≅ ∆ RPQ

• ∆ PQR ≅ ∆ BCA

In ∆ ABC, AB = AC and ∠B = 50°. Then ∠C is equal to

• 40°

• 80°

• 50°

• 130°

In ∆ PQR, ∠R = ∠P and QR = 4 cm and PR = 5 cm. Then the length of PQ is

• 4cm

• 5cm

• 2cm

• 2.5cm

In triangles ABC and PQR, AB = AC, ∠C = ∠P and ∠B = ∠Q. The two triangles are

• isosceles but not congruent

• congruent but not isosceles

• isosceles and congruent

• neither congruent nor isosceles

In triangles ABC and DEF, AB = FD and ∠A = ∠D. The two triangles will be congruent by SAS axiom if

• BC = EF

• AC = DE

• AC = EF

• BC = DE

All the medians of a triangle are equal in case of a:

• Scalene Triangle

• Right angled Triangle

• Equilateral triangle

• Isosceles Triangle

In a triangle ABC, ∠B = 35° and ∠C = 60°, then

• ∠A = 80°

• ∠A = 85°

• ∠A = 120°

• ∠A = 145°

In the given figure, PS is the median then ∠QPS?

• 40^o

• 50^o

• 80^o

• 90^o

In the given figure, if the exterior angle is 135^o then ∠P is:

• 45^o

• 60^o

• 80^o

• 90^o
