Answer 1

Answer:

Obtuse angled triangle

Step-by-step explanation:

As two of the angles are acute angles less than 45° it can't be right angled triangle or acute angled triangle.

Therefore,

Obtuse angled triangle

Answer 2

In a ΔABC. ∠A<∠B<45⁰, then the angle ABC will be an acute angle.

• An acute angle is an angle whose angle never exceeds 90⁰.
• The sum of all three angles in a triangle is 180⁰, so if the angle ABC has less than 45⁰. then the angle is acute.
• An equilateral triangle is always an acute angle since all the angle is 60⁰ which is less than 90⁰.
• An obtuse angle that has an angle greater than 90⁰.
• A triangle consists of three acute angles. It means that all the angles are less than 90 degrees.
