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.

### What is the relationship between isosceles and acute triangles?

They are both triangles. And both have acute angles

Yes

### What type of angles do isosceles triangles have?

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.

### Triangle with all acute angles called?

equilateral triangle, acute triangle, some isosceles and scalene triangles

### What type of triangle has exactly two acute angles?

An Isosceles Triangle.

### What statement sometimes true about the relationship between acute triangles and isosceles triangle?

The two acute angles are always equal.

### How are isosceles triangles and acute triangles alike?

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

### What is anther types of a triangles?

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

### Number of acute angles in isosceles?

An Isosceles triangle has 2 or 3 acute angles.

### Is a triangle an isosceles triangle?

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.

### Are isosceles triangles acute?

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

### Is it true that an isosceles triangle can be acute or obtuse?

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.
