Introduction:
Example:
Using the geometrical properties, solving for finding the third angle of the triangle. The two angles of the triangles are 60°, 45°.
Sol:
Using the geometrical properties of triangle,
The sum of total angle of triangle is 180 degree.
Given two angles are 60°, 45° and consider third angle as z.
Sum of three angles = 180°
60° + 45° + z = 180°
After solving, we get
z = 180° - 105°
z = 75°.
Answer:
The third angle of the triangle is 75°
