acute triangle
A 5-sided polygon, or pentagon, can have a varying number of acute angles, depending on its specific shape. However, the sum of the interior angles of a pentagon is 540 degrees. Since an acute angle is defined as an angle less than 90 degrees, a pentagon can have 0 to 4 acute angles, but typically, it may have 1 to 3 acute angles while still maintaining the overall angle sum.
It could be an irregular 5 sided pentagon.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
A triangle with 3 acute angles is simply called an acute triangle.An example is an equilateral triangle, which has three angles of 60° (acute).
A trapazoid. If the base (Side AB) was 6 cm and the top (Side CD) was 3 cm, then angles A and B would be acute, angles C and D obtuse.
It could be an irregular 5 sided pentagon providing that its 5 inteior angles add up to 540 degrees
this figure has 2 obtuse angles and two acute angles. also the opposite sides are parallel.
