Question

Draw a convex and a non-convex quadrilateral. Find the sum of the measures of the angles
of convex quadrilateral and the non-convex quadrilateral. Is the sum of the angles of convex
quadrilateral and the sum of the measure of the angles of non-convex quadrilateral the same?​

Answer 1

Answer:

1. The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. This property also holds true for a quadrilateral which is not convex.

Answer 2

Answer:

Step-by-step explanation:

A lens having both the spherical surfaces bulging
