Given:-
- The ratio of the measures of angles of a quadrilateral in orders is
- 1:2:1:2.
To Find:-
- Find the measures of its angles & write the type of Quadrilateral.
Concept used:-
- Sum of all angles of Quadrilateral is 360°
Now,
Let the ratio be "x"
So, The angles became x, 2x, x, 2x
Therefore,
→ x + 2x + x + 2x = 360°
→ 6x = 360
→ x = 360/6
→ x = 60
Hence, The Value of x is 60°
So, x = 60 and 2x = 120.
The value of angles of this Quadrilateral is 60, 120, 60 and 120.
→ It is a Parallelogram because opposite angles are equal.

Answer:
Let the angles be n , 2n , n and 2n of quadrilateral
• According to the Question :
⇒ Sum of all angles of Quadrilateral = 360
⇒ n + 2n + n + 2n = 360
⇒ 6n = 360°
⇒ n = 360° ÷ 6
⇒ n = 60°
⠀⠀⠀⠀⠀───────────────
• Measures of the Angles :
◗ n = 60°
◗ 2n = 2(60°) = 120°
◗ n = 60°
◗ 2n = 2(60°) = 120°
If opposite angles are equal i.e. 60° = 60° and 120° = 120° , then the Quadrilateral is Parallelogram.
