If the magnitudes of the two angles of a triangle are 60° and 30°, respectively, what type of triangle is it?
The measure of two angles of a triangle are 60° and 30° respectively.
we know, sum of angles of triangle is 180°
60° + 30° + third angle = 180°
third angle = 180° - 90° = 90°
third angle are = 90°
It is clear that one angle is 90°
Hence, it is right-angled triangle.
