CLASS 9 MATHEMATICS TRIANGLES QUIZ

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

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

An exterior angle of triangle is equal to 100° and two opposite interior angles are equal. Each of the angle is.

It is given that ∆ ABC ≅ ∆ FDE and AB = 5 cm, ∠B = 40° and ∠A = 80°. Then which of the following is true?

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

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

Assertion: Two angles measures a – 60° and 123º – 2a. If each one is opposite to equal sides of an isosceles triangle, then the value of a is 61°. Reason: Sides opposite to equal angles of a triangle are equal.

In triangle ABC, if AB=BC and ∠B = 70°, ∠A will be:

In ∆ PQR, if ∠R > ∠Q, then

It is given that ∆ ABC ≅ ∆ FDE and AB = 5 cm, ∠B = 40° and ∠A = 80°. Then which of the following is true?

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

If two acute angles of a right triangle are equal, then each acute is equal to

An exterior angle of a triangle is equal to 100° and two interior opposite angles are equal. Each of these angles is equal to

Side BC of a triangle ABC has been produced to a point D such that ∠ACD = 120°. If ∠B = 1/2 ∠A is equal to

In a triangle, an exterior angle at a vertex is 95° and its one of the interior opposite angle is 55°, then the measure of the other interior angle is
