Using the cosine rule the biggest angle is: 82.81924422 degrees
Using radius formula for circumcircle of a triangle the radius is: 3.023715784 cm
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Well, honey, that's no ordinary triangle, that's an isosceles triangle. Two sides are the same length, so it's like those twins you can't tell apart. Just make sure to measure those angles too, we don't want any surprises popping up like a bad reality show.
Yes
A scalene triangle.
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.
An isosceles triangle.
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
First you half all the sides, so 4cm, them you multiply by pi, giving the radius as 12pi, or 12.56637061
An equilateral triangle means a triangle with all three sides with equal dimensions. For drawing an equilateral triangle first you will have to choose a measurement to draw the sides of the triangle. For example, lets take the side to be 4cm. When you draw the base of 4cm you will have to draw the other two sides of 4cm as well. Thus an equilateral triangle is constructed..

Yes
It is an equilateral triangle
It is an isosceles triangle with 2 equal sides.
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
radius=4cm diameter=8cm *radius is half the diameter
