Is an arrow convex or concave
WebSimilarly, the arrows in an $\mathbb{R} \to \mathbb{R}$-type picture like the above would be "flopping" inward onto each other, deflated if you will. In the convex mapping the arrows don't overlap at all -- they've got "pressure" or "energy" pushing them outward enough so that they don't overlap. So the image is properly inflated, if you will. WebConvex: Each interior angle measures less than $180^\circ$. Concave: One interior angle is greater than $180^\circ$. A dart or an arrowhead is an example of a concave kite. Properties of a Kite. Let’s learn the important properties of a kite in geometry using the following diagram.

WebBelow are the ray diagram rules for convex mirrors, which allow you to predict where the light rays from an object will travel and then focus in the eye of an observer. Rule 1. Take a line from an object parallel to the principal axis and where it touches the convex mirror take another line to the principal focal point. Rule 2.
