Answer 2

Answer:

Isosceles, obtuse

Step-by-step explanation:

There are three types of triangles based on their sides:

1. Equilateral: a triangle with 3 equal sides
2. Isosceles: a triangle with 2 equal sides
3. Scalene: a triangle with no equal sides

This triangle here as sides of 28 cm, 16 cm, and 16 cm

• This triangle has two equal sides of 16 cm, indicating it is an isosceles triangle

There are three types of triangles based on their angles:

1. Acute: when all angles are less than 90°
2. Right: when the triangle has one angle that is 90°
3. Obtuse: when one of the angles is greater than 90°

This triangle has angles of 26°, 26°, and 128°

• This triangle has one angle that is greater than 90° → 128°, indicating that this is an obtuse triangle
