True
Every square is also a parallelogram as it has all the properties of a parallelogram but vice-versa is not true.
:
We know that, in a trapezium, the angles on either side of the base are supplementary.
In trapezium ABCD,
∴∠A+∠D=180∘⇒55∘+∠D=180∘⇒∠D=180∘−55∘⇒∠D=125∘
:
Number of sides (n), in octagon = 8
Now, the sum of interior angles of a regular octagon =(n−2)×180∘
=(8−2)×180∘6×180∘=1080∘
Since, the octagon is regular, measure of each angle =1080∘8=135∘
:
The diagonals of a kite are perpendicular to each other.
:
20∘
We know that, measure of each exterior angle =360∘Numberofsides=360∘18=20∘.
:
False
We require at least five measurements to construct a quadrilateral.
:
Rhombus or a Square
The length of all the sides are equal in aRhombus or a Square
:
No, it cannot be a rectangle because the diagonals of a rectangle are equal.
:
One
