In this video we are going to look at Similar and Congruent shapes.



Similar and Congruent shapes are seen throughout designs and make it much easier. In this image, only two shapes have been drawn and then by...

👉 Learn how to evaluate the limit of a function involving rational expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The...

👉 Learn how to reflect points and a figure over a line of symmetry. Sometimes the line of symmetry will be a random line or it can be represented by the x or y-axis. Either way when reflecting a point and or figure over the line of...
