Triangles
Acute angles
There are many possible shapes with two acute angles.
some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
A triangle is the only shape that can have only acute angles inside it.
Shapes that do not have right angles include circles, ovals, and various types of polygons such as triangles (specifically acute and obtuse triangles), and irregular polygons. Additionally, shapes like ellipses and curves, such as parabolas, also lack right angles. These shapes can have angles of varying degrees, but none equal to 90 degrees.
you could count the sides or acute, obtuse, or right angles.
a traingle, sometimes
Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
A polygon, that is, a plane area bounded by any number (>2) of straight lines can have acute angles.
There are no acute angles in a rectangle which has 4 equal interior right angles
Yes, acute angles and right angles are different. An acute angle is less than 90 degrees - a right angle is exactly 90 degrees.
