Answer:
Isosceles, obtuse
Explanation:
There are three types of triangles based on their sides:
- Equilateral: a triangle with 3 equal sides
- Isosceles: a triangle with 2 equal sides
- 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:
- Acute: when all angles are less than 90°
- Right: when the triangle has one angle that is 90°
- 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
