Scalene
Yes, an equilateral triangle has 3 congruent sides.
A scalene triangle is a triangle that does not have a right angle in it (i.e. not a right angled triangle) and does not have two (or three) sides with the same length (i.e. not an isosceles triangle or an equilateral triangle). An example is a triangle with sides of length 4cm, 5cm and 6cm.
No.
How many sides has a square got? (4) So if all the sides are 6cm. Perimeter = 6 + 6 + 6 + 6 How many sides does an equilateral triangle have? (3) All the sides are the same length in these shapes so again: Perimeter = 6 + 6 + 6
No because the dimensions given relate to an isosceles triangle.
Scalene
A scalene triangle is simply a triangle where all of its sides are different lengths. One example of the side lengths of a scalene triangle are: 5cm, 6cm and 7cm
A right triangle cannot have those lengths, so no.It would be a scalene triangle (no sides are the same)

No.
22cm
No
Yes, it can. And if you do the math, some basic trigonometry, you can calculate the angles in the triangle.

Probably an equilateral triangle
