Question

A triangle ABC can be formed when, $\angle$ ABC = 60°, $\angle$ BCA= 60° and $\angle$ CAB=90°

• A. True
• B. False

Answer 1

The correct option is A

True

In any triangle, we know that the sum of all the angles of a triangle is equal to 180°, (Angle Sum Property)

Therefore,

$\angle$ ABC + $\angle$ BCA + $\angle$ CAB = 180°

On Substituting for $\angle$ ABC , $\angle$ BCA and $\angle$ CAB ,

we get

60° + 60° + 90° = 210 ° which is not equal to 180°

A triangle cannot be formed with the given measurement
