An Isosceles triangle has 2 or 3 acute angles.
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.
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
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
An isosceles triangle can have an obtuse angle and two equal acute angles in which all 3 angles add up to 180 degrees.
