an equilateral triangle
acute triangle
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.
A three sided shape is a triangle but the given angles are incorrect because a triangle can't possibly have a right angle and an obtuse angle because its 3 interior angles must add up to 180 degrees.
For any quadrilateral (i.e. 4-sided figure), the angles will add up to 360 degrees. Since an obtuse angle is any angle with a measurement over 90 degrees, it is possible to have a quadrilateral with 3 obtuse angles. The fourth angle, however, must be acute (i.e. smaller than 90 degrees). Having 3 obtuse angles is not a requirement, however, for a quadrilateral.
A 3-sided figure is called a triangle.
