Answer: statement 2: a square is always a rhombus.
Step-by-step explanation:
A parallelogram does not have all the interior angle as right angle.
Therefore, it does not satisfy property of rectangle.
A square has all sides equal and its diagonals are perpendicular bisector.
Thus, square satisfies all the properties of rhombus .
A rectangle does not have all the sides are equal.
Therefore, it cannot b e a square.
Answer:
angle AOD = 90⁰
BOD = 3x⁰
90⁰+3x⁰ = 180⁰( being straight angle)
3x = 180⁰-90⁰
3x = 90⁰
x = 90⁰/3
x = 30⁰
now
y⁰+139⁰ = 180⁰(being straight angle)
y⁰ = 180⁰-139⁰
y⁰ = 41⁰
