an acute triangle (each angle less than 90 degrees), a right triangle (one angle equal to 90 degrees), and an obtuse triangle (one angle greater than 90 degrees). Find the perimeter for each of these triangles
can you give me a perimiter for each of these kind of triangles?

can you just maske one up and tell me the perimiter of it?
i really need this please help

You just add the sides of each triangle to get the perimeter. We can't help you any further than that without more details about each triangle.

Well, to get the perimeter, just add the 3 sides together.
Acute triangle: Equilateral, side 1, perimeter 3.
Right triangle: 3,4,5 (since a²+b² = c²), perimeter 12.
Obtuse triangle, 1,2 â7. (Why? Because c² = a²+b²+ab,
so this is a 120 degree triangle, by the law of cosines.)
Perimeter: 3 + â7.

The perimeter for any triangle = Sum of its sides
And dont depend on his type or angle of it
if sides are a,b,c
a=5mm
b=4mm
c=3mm
perimeter=5+3+4=12mm

The perimeter? That's impossible to tell without having more information. You can obviously pick two different triangles of any of these three types and come up with two different values for the perimeter.

P = sum of all the sides. doesn't matter what kind it is.
