The given trianagle FAN is an acute triangle.
Step-by-step explanation:
There are three types of triangles on the basis of angle:
- Acute triangle: All three angles are less than 90°
- Obtuse triangle: One out of three angles is greater than 90°.
- Right-angled triangle: One of the measurements of an angle will be equal to 90°.
(As shown in image attached)
Given:
A triangle FAN with an angle measurement of each angke.
To find:
The name adjoining triangle FAN on the basis of angle.
Solution:
In ΔFAN
∠A=55°, ∠F=85° ,and ∠C=45°
∠A<90°, ∠F<90° ,and ∠C<90°
All the given three angles of triangle FAN are less than 90°, which imolies that the given trianagle FAN is an acute triangle.
