Angles and Similarity
Experiment with the measures of the angles of similar triangles to determine conditions necessary for two triangles to be similar.
Applications of Similar Figures
Students will identify corresponding parts of figures and use the definition of similar figures to solve real-world applications involving rectangles and triangles.
Corresponding Parts of Similar Triangles
Change the scale factor (r) between similar triangles; identify the corresponding parts and establish relationships between them.
Nested Similar Triangles
Discover the conditions that make triangles similar by moving the sides opposite the common angle in nested triangles.
Ratios of Similar Figures
Students explore the ratio of perimeter, area, surface area, and volume of similar figures in two and three dimensional figures.
Scale Factor Area Perimeter
Explore the relationship of perimeter and area in similar triangles when the scale factor is changed.
Observe what happens to ratios of pairs of side of rectangles and triangles.
Investigate the relationships between a triangle and the similar triangle formed by one of the triangle's midsegments.
