Question

6. CAN A TRIANGLE HAVE THREE ANGLES WHOSE MEASURES ARE
1) 65° , 74° , 39°? 2) 1/3 right angle , 1 right angle , 60°?
[ Hint. find the sum of angles. ]

Answer 1

$\huge\bf\boxed {ANSWER}$

1)

65°, 74°, 39°

Sum of all angles= 65 + 74 + 39

Sum of all angles= 178°

=> No. bcoz the sum of all angles in a triangle is 180°.

2)

1/3 right angle, 1 right angle, 60°

=> 1/3 right angle = 90/3 = 30°

=> 1 right angle = 90°

Sum of all angles = 30 + 60 + 90

Sum of all angles = 180°.

=>Yes. bcoz the sum of all angles is 180°
