Best Answer

Answer: Yes, because of the two angles have to be exactly equal in order to be isosceles. And no isosceles has 3 acute angles and then it will be equilateral triangle

Answer: No, the isosceles triangle can either have two acute angles, or all three can be acute.

They are both triangles. And both have acute angles

Yes

equilateral triangle, acute triangle, some isosceles and scalene triangles

Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.

An Isosceles triangle has 2 or 3 acute angles.

Yes

Isosceles triangles have two equal sides. The angles opposite the equal sides are also equal. For instance, if the top angle is 48o and the two bottom angles are 66o an acute isosceles triangle is formed.

An Isosceles Triangle.

The two acute angles are always equal.

They both have 3 sides and 3 interior angles that add up to 180 degrees.

Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.

It can be, if two of the sides and two of the angles are equal. Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.

Yes, the top angle is less than 90 degrees so it would be acute. Same with the bottom angles.

Yes, it is true that an isosceles triangle can be acute or obtuse. As long as a triangle has two equal angles and two equal sides, it is isosceles. That situation can occur in both acute (all angles less than 900) and obtuse (one angle more than 900) triangles. Examples are a triangle with the angles being 75-75-30 degrees (acute) and one having angles of 120-30-30 (obtuse). Of course the sides of the angles that are equal would also be equal, so both examples are of isosceles triangles.
