This is convex lens leadership.

What does that convex lens do?

So I learned the lesson of convex lens leadership from that.

And in a convex lens, it'll be symmetric. So let me see if I can draw it. One side of the lens will look like that.

Since the slope of the convex lens surface increases outwards, separation of the rings gets smaller for the outer rings.

In the last video, I showed that a bunch of triangles are similar to each other to come up with a relationship between the focal length, the distance of an object from the convex lens, and the distance of the image of an object from that convex lens.

One day he took us out into the sun and tried to show us how to find the focal length of a convex lens.

Convex Polygon Test

This polygon is convex.

This polygon is not convex.

In mathematics, convex geometry is the branch of geometry studying convex sets, mainly in Euclidean space.

Check whether this polygon is convex

So this right over here is what a convex quadrilateral, this is what a convex quadrilateral could look like.

So you have concave, and you have convex.

So one type of convex quadrilateral is a trapezoid.
