Given :
The four angles of a quadrilateral in the radio 1:2:3:4
To Find :
Measure of each angle of the quadrilateral
Solution :
Let angles be x , 2x , 3x , 4x respectively
We know that , " Sum of angles in a quadrilateral is 360° "
⇒ x + 2x + 3x + 4x = 360
⇒ 10x = 360
⇒ x = 36°
→ x = 36° ←
→ 2x = 2(36) = 72° ←
→ 3x = 3(36) = 108° ←
→ 4x = 4(36) = 144° ←
More Info :
- Sum of angles in a straight line is 180°
- Sum of angles in a triangle is 180°

➳ X + 2X + 3X + 4X = 360°
➳ 10X = 360°
➳ X = 360/10
➳ X = 36°
The four angles of the quadrilateral are,
- = 36°
- = 2 × 36° = 72°
- = 3 × 36° = 108°
- = 4 × 36° = 144°
