उत्तर
A triangle can be constructed by taking two of its angles as 110°, 40°.
Explanation:
We know that, the sum of all the angles of a triangle is equal to 180°.
So, sum of any two angles of a triangle should be less than 180°.
110° + 40° = 150° i.e. less than 180°
70° + 115° = 185° i.e. greater than 180°
135° + 45° = 180° i.e. equal to 180°
90° + 90° = 180° i.e. equal to 180°.
