It is a triangle.
A rhombus is a shape having two acute angles and four equal sides.
An acute isosceles triangle has three acute angles (
They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.
It has no equal sides and no equal angles. It can be acute or not. So the answer is it can be.
They are equal.
It is a rhombus which has 2 equal acute angles and 2 equal obtuse angles
triangle
Any triangle that has three equals sides must have three acute angles and is equilateral.
Its sides are congruent but not its angles because it has 2 equal opposite acute angles and 2 equal opposite obtuse angles.
An isosceles triange has 2 equal sides and 2 equal interior angles whereas an acute triangle has 3 unequal sides and 3 interior acute angles of different sizes
equiangular equilateral
An isosceles triangle fits the description given or an equilateral triangle which has 3 equal sides and 3 equal acute angles.
