This mini-lesson introduces and walks you through the basic concepts of congruency and similarity. You'll learn it with the help of some examples and practice questions with solution, using video explanations and own handwriting by the instructor that brings in an element of real-class room experience.
Congruence means that they are exactly the same and similarity means that they look the same, but are of different sizes. E.g. two triangles are congruent if everything about them is the same: angles, side lengths, etc. In case you have a small triangle and a big triangle, but they have the same angles, they are similar – they are not the same, but they share many properties. You will also find explanation of determining unknown dimensions or angles without measuring.
