Question

Can u please tell me this​

Answer 1

Answer:

• 1) no, if three vertex of current will be collinear that it become triangle
• 2) false, because the sum of all sides is 360 obtuse angle can be can we become it only need 90 and more degree
• 3)true,because the sum of three annual should be 180 if two angle are right then do it can sum of three

angles be 180.

• 4) no, it is because one of internal angle of any character is 360 it does not matter whether the quadrilateral is concave or convex one of the angle is more than 180.
• 5) true,the median is a line of line segment of one side of triangle and its opposite vertex.

Answer 2

Answer:

1)=False=Reason=No, three vertices of a quadrilateral are never collinear, and if we do it, then it will become a triangle.

2)=False=Reason=It is possible for a quadrilateral to have an obtuse angle.

3)=False=Reason=We have some quadrilaterals which have more than one right angle like Rectangle, Square, Trapezoid.

4)=False=Reason=It is not for a quadrilateral to have sum of its all angles more than 360°, whether it is concave or convex.

5)=False=Reason=A diagonal of a quadrilateral cannot join any vertices of the quadrilateral, it only joins the opposite vertices.

6)=True=Reason=Only Concave quadrilateral has an angle more than 180°.
