Question

A triangle can be constructed by taking two of its angles as ______.

विकल्प

• 110°, 40°

• 70°, 115°

• 135°, 45°

• 90°, 90°

Answer 1

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°.
