Answer:
All statements are true.
Step-by-step explanation:
In a square, we have
all sides equal
all angles equal to 90 degrees
diagonals always bisect each other and at right angles.
Only square is the quadrilateral which satisfies all the above properties.
A parallelogram has diagonals which do not cut at right angles.
A rhombus has all sides equal but not all angles. Neither diagonals are equal in a rhombus.
Answer:
The value of x = 12.
Step-by-step explanation:
We know that two angles are termed as supplementary when the sum of the measure of their angles is 180°.
We also know that a straight line angle measures 180°.
It is clear that the angles 72° and 9x° line on a straight line. Thus, the sum of the measure of their angles is 180°.
Therefore,
9x° + 72° = 180°
9x° = 180° - 72°
9x° = 108
divide both sides by 9
9x/9 = 108/9
x = 12
Therefore, the value of x = 12.
Answer:
If I'm not mistaken that is the answer
Across the largest side is going to be largest angle, and across the smallest side -smallest angle.
Sides:
BC = 9 < AB = 13 < CA = 17.
Angles that are across sides: A < C < B.
Answer is d- A C B.
