+Question 6.1 & 6.2 – 10
+Answer 6.1 & 6.2 – 10
The figure is a concave polygon. It has more than three sides. Each side is intersected by another side at either endpoint and each side in a segment (not curved).
+Question 6.1 & 6.2 - 20
+Answer 6.1 & 6.2 – 20
The figure is not a polygon because two sides are not intersected at both sides by another side.
+Question 6.1 & 6.2 - 30
+Answer 6.1 & 6.2 – 30
The m D is 120o. The sum of the measures of the interior angles of quadrilateral is 360o.
+Question 6.1 & 6.2- 40
+Answer 6.1 & 6.2 – 40
A. Pentagon (5 sides)
+Question 6.1 & 6.2 - 50
+Answer 6.1 & 6.2 – 50
J. 45o. The sum of the measures of the interior angles of quadrilateral is 360o.
+Question 6.3 - 10
+Answer 6.3 – 10
C. Bisect each other
+Question 6.3 - 20
+Answer 6.3 – 20
y = 7x = 61
+Question 6.3 – 30
+Answer 6.3 – 30
y = 110x = 100
+Question 6.3 - 40
+Answer 6.3 – 40
The quadrilateral is a parallelogram because the diagonals bisect each other.
+Question 6.3 - 50
+Answer 6.3 – 50
The quadrilateral is not a parallelogram because the opposite angles are not congruent.
+Question 6.4 - 10
+Answer 6.4 – 10
That all four angles are right angles.
+Question 6.4 - 20

+Question 6.6 - 40
+Answer 6.6 – 40
+Question 6.6 - 50
+Answer 6.6 – 50
Yes, because opposite sides are congruent and one angle is given as right, the other angles must also be right.
