Question

F) If two angles of a triangle measures 63° and 27°, then it is a/an
(i) Acute angled triangle

(iii) right angled triangle
(ii) obtuse angled triangle
(iv) none of these​

Answer 1

Answer:

acute angle hope you mark on our bain list

Answer 2

Option (iii) right angles triangle is correct.

• If two angles of a triangle measures 63° and 27°, then it is a right angled triangle.

Explaination :–

Right angled triangle = 90° and the given measures of the angles are 63° and 27°.

So,

63° + 27° = 90°

The sum of both the angles is 90°.

So, this is a right angled.

Let's talk about all the options.

• (i) Acute angled triangle.

Acute angle is less than 90°.

But the sum of the given measures is 90° which is not less than 90°.

So, this is the wrong option.

• (ii) Obtuse angled triangle.

Obtuse angle is more than 90°.

But the sum of the given measures is 90° which is not more than 90°.

So, this is the wrong option.

• (iii) Right angled triangle.

Right angle is correct 90°.

The sum of the given measures of two angles is 90°.

So, this is the correct option.

• (iv) none of these.

This option is also wrong because (iii) option is correct.
