Question

Please answer me my questions and correct ​

Answer 1

Answer:

1. The sum of all measures of a convex quadrilateral is 360 degrees.

2. The expression is (n-2) * 180

Example:-

Triangle = (3-2)*180 = 180

Quadrilateral = (4-2)*180=360

Answer 2

Answer:

1. the sum of of all the interior angles of a convex quadrilateral is 360°

2. the expression that can be used to find the sum measure of all angles of all interior angles of a polygon having n sides is

(n-2) x 180

for example:- in a quadrilateral, 4 sides are there . so using this formula we can find out measure of all interior angles

(4-2) 180

2x180

360°
