They are both triangles. And both have acute angles
equilateral triangle, acute triangle, some isosceles and scalene triangles
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.
For the "catch all" and most broad type of triangles, there are 3: Obtuse - 1 angle > 90° Acute - all angles < 90° Right - 1 angle exactly 90° There are more specific categories, such as isosceles triangles, which can be obtuse, right or acute triangles that contain exactly 2 angles of equal degree, and exactly 2 sides of equal lengths.
An Isosceles triangle has 2 or 3 acute angles.
Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.
They both have 3 sides and 3 interior angles that add up to 180 degrees.
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.
