Question

Assertion : In ∆ABC, ∠C = ∠A, BC = 4 cm and AC = 5 cm. Then, AB = 4 cm Reason : In a triangle, angles opposite to two equal sides are equal. *

A and R are true and R is correct explanation of A.
A and R are true and R is not the correct explanation of A.
A is true but R is incorrect.
A is incorrect but R is true

Answer 1

Answer:

Angle A is smallest

Angle Opposite to smallest side is smaller

BC is the smallest side

So angle A is small

Answer 2

Given :  Assertion : In ∆ABC, ∠C = ∠A, BC = 4 cm and AC = 5 cm. Then, AB = 4 cm

Reason : In a triangle, angles opposite to two equal sides are equal. *

To Find : Choose correct option

Solution:

Assertion : In ∆ABC, ∠C = ∠A

=> AB = BC  as side opposites to equal angles in a triangle are equal

BC = 4 cm

=> AB = 4 cm

Hence Assertion is correct

Reason : In a triangle, angles opposite to two equal sides are equal.

Correct

Reason is correct explanation of the Assertion

A and R are true and R is correct explanation of A.   is the correct option :
