Question

Assertion : If two internal opposite angles of a triangle are equal and external angle is given to be 110°, then each of the equal internal angle is 55°. Reason : A triangle with one of its angle 90, is called a right triangle

Answer 1

Step-by-step explanation:

asssertion and reason are correct

Answer 2

Given: ASSERTION – If two interior opposite angles of a triangle are equal and external angle is given to be 110° , then each of the equal interior angle is 55° .

REASON – A triangle with one of its angle 90° , is called a right angle triangle .​

To Find :  True/False

Solution:

ASSERTION – If two interior opposite angles of a triangle are equal and external angle is given to be 110° , then each of the equal interior angle is 55° .

External angle of a triangle = sum of opposite interior angles

two interior opposite angles of a triangle are equal

=> 110°  = x + x

=> 110°  = 2x

=> 55°  = x

Hence True

REASON – A triangle with one of its angle 90° , is called a right angle triangle .​

TRUE

ASSERTION  and Reason are correct

But reason is not the correct explanation of Assertion
