Chapter 8 Transformations and Constructions

The plan is the view from above the solid. The front elevation is the view of the front of the solid. The side elevation is the view of the side of the solid. In this section, we learn about 3D Solids, Plans and Elevations of 3D Solids, plan and elevation views, How to draw pyramids, How to draw cuboid, How to construct rectangular prism.

A reflection is a flip of a shape that is mirrored across a line or a point, while a rotation is the circular motion of an object around its center. In this section, we learn about transformations reflection basic, transformations rotation, reflection, reflection along diagonal, rotation.

Enlargement is a type of transformation that changes the size of a shape by making it bigger or smaller by multiplying its side lengths by a scale factor. In this section, we learn about Enlargement, enlargement with positive scale factor, enlargement with negative scale factor.

A translation is a type of transformation that slides each point in a figure the same distance in the same direction. In this section, we learn Translation, all transformations, combination of transformations.

Bearing is defined as an angle measured clockwise from north. Bearings are usually written as a three-figure bearing. For example, the angle 50° from north is written as 050°. In this section, we learn about Bearings, Ratio Scale, Scale drawings, Constructing scale drawings.

To construct means to draw accurately using a ruler and compasses. In this section, we learn about Construction, how to construct the Perpendicular bisector, how to construct a perpendicular line from a point off the line, types of constructions of triangle.

An angle bisector cuts an angle exactly in half. In this section, we learn about Basic Geometry Drawing, how to draw an angle of 60, how to construct an angle bisector.

A locus is the set of all points that obey a certain rule. Often a locus is a continuous path. A circle is the locus of a point that that moves so that it is always a fixed distance from a fixed point. In this section, we learn about Introduction to circle, locus.
