In this lesson, students will learn how to determine if two triangles of different sizes are similar. The lesson focuses on using translations to establish triangle similarity.

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

👉 Learn how to solve problems with rectangles. A rectangle is a parallelogram with each of the angles a right angle. Some of the properties of rectangles are: each pair of opposite sides are equal, each pair of opposite sides are...

This video explains the concept of similarity and congruency of triangles and how the areas of similar triangles change with the scale factor. It also provides a theorem that states the ratio of areas of similar triangles is equal to the...

Through real life examples and animation, this video shows students that when an object is symmetrical, it has the property of symmetry and that the line of symmetry is the line of reflection. Students will come to understand that many...

In this video, students learn how to determine if two figures are congruent by using a sequence of transformations. Learn about three types of rigid transformations - rotations, reflections, and translations - and understand how to apply...

In this video lesson, students learn about the properties of triangle angles. They discover that the sum of the three angles in a triangle always adds up to 180 degrees, regardless of the type of angles involved. The lesson also...
