Explanation:

Step1: Identify triangle - 1

It has a right - angle and all sides are unequal. So it is Right and Scalene.

Step2: Identify triangle - 2

It has a right - angle and two equal sides. So it is Right and Isosceles.

Step3: Identify triangle - 3

All angles are acute and all sides are equal. So it is Acute and Equilateral.

Step4: Identify triangle - 4

All angles are acute and two sides are equal. So it is Acute and Isosceles.

Step5: Identify triangle - 5

All angles are acute and all sides are unequal. So it is Acute and Scalene.

Step6: Identify triangle - 6

It has an obtuse - angle and two equal sides. So it is Obtuse and Isosceles.

Answer:

1. Right, Scalene
2. Right, Isosceles
3. Acute, Equilateral
4. Acute, Isosceles
5. Acute, Scalene
6. Obtuse, Isosceles
