Answer:
<em>>regular triangle, we call equilateral triangles </em><em>regular polygons.</em>
<em>>isosceles, as an equilaterial triangle is a </em><em>specific type of isosceles </em><em>due to more than one side being of equal length and angle.</em>
<em>>equilateral, where </em><em>all sides and angles are the same.</em>
<em>>acute, as all </em><em>3 angles are less than 90</em>
<em>>equiangular. equilateral triangles are also</em><em> described as equiangular.</em>
Step-by-step explanation:
<em>Just the five ways above can describe the polygon shown, as the angles of a scalene triangle are unequal. as are their sides, equilaterial have same sides and angles. Obtuse have angles larger than 90deg less than 180 deg. </em>
<em>Whilst irregular are triangles and shapes that have uneven sides and are not right or isosceles.</em>
<em>Right triangles have one angle that is exactly 90 deg.</em>
