Answer 1

5.If a figure can be folded or divided into half so that the two halves match exactly then such a figure is called a symmetric figure. The figures below are symmetric. The dotted line in each of the symmetric figures above that divides the figure into two equal halves is called the line of symmetry.

6.multiples of 13 are 13, 26, 39, 52.

8.In Mathematics, “an obtuse angle is an angle which is greater than 90° and less than 180°”. In other words, an obtuse angle is between a right angle and a straight angle.

11. P=2(l+b)

P=2(4+9)

=2(13)

P=26cm
