Classify the following triangle check all that apply

The correct options are A) Equilateral, C) Acute and E) Isosceles.

Step-by-step explanation:

Consider the provided triangle:

Equilateral triangle: A triangle is said to be an equilateral triangle if all sides are equal.

Obtuse triangle: A triangle is said to be Obtuse triangle if one angle is greater than 90°.

Acute triangle: A triangle is said to be Acute triangle if all the 3 angles are less than 90°.

Right triangle: A triangle is said to be Right triangle if one angle is equal to 90°.

Isosceles triangle: A triangle is said to be the Isosceles triangle if it has at least two sides of equal length.

Scalene triangle: A triangle is said to be Scalene triangle if all the three sides have different length.

Now consider the provided figure:

All sides and angles of the provided triangle are equal. Also, the angles are less than 90°.

Thus, the triangle is:

Equilateral triangle because all the sides are equal.

Acute triangle because all the three angles are less than 90°.

Isosceles triangle because more than two sides are equal.

Hence, the correct options are A) Equilateral, C) Acute and E) Isosceles.
