Answer 2

Answers:–

1) 0

2) 6

3) 900°

4) If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°.

5) triangle

6) hexagon

7) Sum of the exterior angles of a polygon. Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees.

8) We know that, sum of all the 1 angles of a quadrilateral is 360°. Hence, the fourth angle of a quadrilateral is 120°.

9) The measure of each angle is 360/4 = 90°. The so formed quadrilateral is a rectangle or a square.

10) Let angle A =angleC

and,angle B =angle D

A.T.Q

angle C= angle A

130degrees =130degrees

angle D = angle B

40degrees = 40degrees

AngleA=130degrees

AngleB=40degrees

AngleC=130degrees

Angle D= 40degrees

11) rectangle:–

A parallelogram with one right angle is a rectangle. A quadrilateral whose diagonals are equal and bisect each other is a rectangle.

12)1. If one angle of a parallelogram is of 65°, then the measure of the adjacent angle is *

65°

25°

90°

115°

Other:

2. If ˂A of a parallelogram A B C D is of 60°, then the measure of the opposite angle ˂C is *

60°

120°

30°

None of these

Other:

3. If all the four sides of a parallelogram are equal and the adjacent angles are of 120° and 60°, then the name of the quadrilateral is *

Rectangle

Square

Rhombus

Kite

Other:

4.If the length of a side of a rhombus is 6cm, then the perimeter of the rhombus is *

6 cm

12cm

24cm

3cm

13) 6cm

14)The sum of the interior angles of a regular polygon of 10 sides = 10*[180 - (360/10)] = 10(180–36) = 10*144 = 1440 deg.

15) Square:–

Square is a quadrilateral with four equal sides and angles. It's also a regular quadrilateral as both its sides and angles are equal. Just like a rectangle, a square has four angles of 90° each. It can also be seen as a rectangle whose two adjacent sides are equal.

Hope this helps you.
