Because an edge of an isosceles triangle can be greater than 90° occasionally an acute triangle is not an isosceles.

You are watching: Determine if the statement is always, sometimes or never true. an acute triangle is isosceles.

Sometimes

Step-by-step explanation:

An acute triangle is a triangle with all of its three angles room acute (i.e. Less than 90°).

An isosceles triangle is a triangle which has actually two sides of same length.

We recognize that angles opposite come the equal sides of a triangle room equal.

Therefore, a isosceles triangle is a triangle which has two angles room equal.

An acute triangle is occasionally isosceles triangle

For example :- Equilateral triangles is acute triangle and also it is also a isosceles triangle.

Consider a triangle v angles 40°,40°,100°

It is isosceles but not acute.

An acute triangle is occasionally isosceles triangle

Step-by-step explanation:

we need to determine the statement true or not

"An acute triangle is isosceles"

An acute triangle is a triangle with every one of its angles space acute (i.e. Much less than 90°).

An isosceles triangle is a triangle which has two political parties of same length.

We understand that angle opposite to the same sides of a triangle room equal.

∴ one isosceles triangle is a triangle which has two angles room equal.

An acute triangle is occasionally isosceles triangle

Eg :- Equilateral triangle is acute triangle and also it is additionally a isosceles triangle.

Consider a triangle through angles 40°,40°,100°

It is isosceles yet not acute.

Hence, Correct alternative is sometimes.

Sometimes

Step-by-step explanation:

By definition:

Isosceles triangle:Two same sides and

Two equal angles

Acute triangle: All angles are much less than 90°.

Because an edge of an isosceles triangle can be higher than 90° sometimes an acute triangle is no an isosceles.
