QUESTION: 1

In the given figure, AB = AC, AD = AE = 5 cm and DC = 8 cm. Length of EB is.

Solution:
8 cm is the answer because DC =EB=8 cm.

QUESTION: 2

Triangle ABC is congruent to triangle DEF. Which side is congruent to side BC?

Solution:

QUESTION: 3

Which of the following statements is incorrect ?

Solution:

QUESTION: 4

In the following figure, PQ = PR and SQ = SR, then

Solution:

QUESTION: 5

If two triangles ABC and PQR are congruent under the correspondence A ↔ P, B ↔ Q and C ↔ R, then symbolically, it is expressed as

Solution:

QUESTION: 6

If ΔABC ≌ ΔPQR then which of the following is true:

Solution:

QUESTION: 7

If two sides of a triangle are equal, the angles opposite to these sides are

Solution:

QUESTION: 8

In case of two equilateral triangles, PQR and STU which of the following correspondence is not correct

Solution:

QUESTION: 9

In quadrilateral ABCD, AB bisects ∠A. Which of the following criterion will prove ΔABC ≅ ΔABD?

Solution:

In quadrilateral ABCD we have

AC = AD

and AB being the bisector of ∠A.

Now, in ΔABC and ΔABD,

AC = AD

[Given]

AB = AB

[Common]

∠CAB = ∠DAB [∴ AB bisects ∠CAD]

∴ Using SAS criteria, we have

ΔABC ≌ ΔABD.

∴ Corresponding parts of congruent triangles (c.p.c.t) are equal.

∴ BC = BD

QUESTION: 10

In an isosceles triangle ABC with AB = AC, if BD and CE are the altitudes, then BD and CE are

Solution:

QUESTION: 11

In fig., if AB = AC and PB = QC, then by which congruence criterion PBC ≅ QCB

Solution:

As AB=AC so angle ACB=angleABC as angles opposite to equal sides r equal. In trianglePBC and Triangle QCB we see that

I)PB=QC(given)

ii)anglePBC=angleQCB(proved earliar)

iii)BC=BC(common) so triangle PBC is congruent to triangle QCB by SAS axiom of congruency.

QUESTION: 12

The diagonal PR of a quadrilateral PQRS bisects the angles P and R, then

Solution:

QUESTION: 13

In the given figure, AB = EF, BC = DE, AB ⊥ BD and EF ⊥ CE. Which of the following criterion is true for ΔABD ≅ ΔEFC?

Solution:

QUESTION: 14

Two figures are congruent if they have

Solution:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

QUESTION: 15

A triangle can have:

Solution:

The least number of acute angles that a triangle can have is 2.

As we cannot have more than one right angle or obtuse angle, we have only two or three acute angles in a triangle.

Further, if one angle is acute, sum of other two angles is more than 90 deg and we cannot have two right angles or obtuse angles.
