Samuel Chukwuemeka (Samdom For Peace) B.Eng., A.A.T, M.Ed., M. A reflection in a line k parallel to the direction of the translation maps P’ to P. If you are my student, please do not contact me here. Please check back for the remaining ones later.Ĭomments, ideas, areas of improvement, questions, and constructive criticisms are welcome. They will also solve problems in Vector Geometry. Extended learners will apply vectors to real life problems including finding the magnitude and direction of a vector. The calculators should work.Īt the moment, only the calculators for the Translations, Reflections, and Rotations are completed. For instance learners will understand how vectors can be used to describe the translation of shapes by plotting the translation of each of the individual points. I wrote the codes for these calculators using Javascript, a client-side scripting language. Solution: In general In this case, P(2,2) ,P(x,y)P(x+a,y+b). The rigid transformations are translations, reflections, and rotations. For example, we can translate a point by moving it 5 units left and 3 units up. Translation is an example of a transformation. A translation is a way to move a point or shape by a certain number of units in a certain direction. (b) More generally than in (a), given any fixed line m, let f be the mapping defined by reflection in the line m. A rigid transformation (also known as an isometry or congruence transformation) is a transformation that does not change the size or shape of a figure. A translation moves a shape up, down or from side to side but it does not change its appearance in any other way. Hence f maps the family of all lines in Euclidean plane geometry onto itself - hence f is a geometric transformation of Euclidean plane geometry.

Then use the calculators to check your answers. A transformation is an operation that moves, flips, or otherwise changes a figure to create a new figure. You are encouraged to: solve the questions graphically (by construction) verify the solutions algebraically (by formulas) ment of the euclidean geometry is clearly shown for example, it is shown that the whole of the euclidean geometry may be developed without the use of the axiom of continuity the signi-cance of Desargues’s theorem, as a condition that a given plane geometry may be regarded as a part of a geometry of space, is made apparent, etc. Third: solve the questions/solved examples.įourth: check your solutions with my thoroughly-explained solutions.įifth: check your answers with the calculators as applicable.
