a triangle is 180 degrees a square is 2 triangles so it is 360 degrees an octagon is 8 sides 720 degrees 180 times 4 = 720 degrees
a rectangle and octagon are alike because they both are quadrilaterals.
They are polygons
No because an octagon has 8 sides whereas a triangle has only 3 sides but they are both polygons.
Three is to triangle as eight is to octagon.
they are alike because they both have acute angles

the number of sides
Triangle, octagon, and my favorite, dodecagon.
