whats a consecutive side and whats a consecutive angle?

For consecutive sides of a polygon, it is any two sides which connect with a single point.

Can you explain what the difference between rounding and front end estimation is? For example round 8267-2761= and front end estimate 6489-1807= . I a

In geometry, when we talk about consecutive sides and consecutive angles, we are referring to the arrangement of sides and angles in a polygon.

Consecutive sides: In a polygon, consecutive sides are the sides that share a common vertex or endpoint. For example, in a triangle, side AB and side BC are consecutive sides because they share the common vertex B.

Consecutive angles: Similarly, in a polygon, consecutive angles are the angles that share a common side. For example, in a triangle, angle A and angle B are consecutive angles because they share the common side AB.

To determine which sides or angles are consecutive, you can look at the order in which they appear in the polygon, usually in a clockwise or counterclockwise direction. Just remember that consecutive sides share a vertex, while consecutive angles share a side.

It's important to note that the concept of consecutive sides and consecutive angles is applicable to all polygons, including triangles, quadrilaterals, pentagons, and so on.
