SIMILAR TRIANGLES Similar figures have the same shape, but are a different size.
SIMILAR TRIANGLES Corresponding sides of similar figures are proportional. 2" 4" 3" 6"
SIMILAR TRIANGLES Using proportions, we can find the lengths of missing sides of similar figures. 6" 12" 4" ?
SIMILAR TRIANGLES 6" 12" 4" x = x
6" 12" 4" x = x x = 48÷6 = 8"
SIMILAR TRIANGLES 6" 12" 4" ? = x
6" 12" 4" x = x x = 48÷6 = 8"
SIMILAR RECTANGLES 7"x 4" x 8"
7"x 4" x 7 x 4 = 8 8"
7"x 4" x 7 x 4 = 8 8" x = 14"
SIMILAR RECTANGLES 7"x 4" x 7 4 x = 8 8"
7"x 4" x 7 4 x = 8 7.5" x = 14"
SIMILAR RECTANGLES 5" 8" x 10"
5" 8" x = x 10"
5" 8" x = x 10" x = 16"
SIMILAR RECTANGLES 5" 8" x = x 10"
5" 8" x = x 10" x = 16"

I can use proportions to find missing lengths in similar figures.
I can find missing lengths in similar figures and use similar figures when measuring indirectly.
You can use similar figures to find missing information about one of the figures, when you know the measurements of at least one of the figures and.
6.4 Similar and Congruent Figures Similar Figures - t wo figures that have the same shape but not necessarily the same size We use this symbol to show.
7-4A Similar Figures and Proportions Learning Objective: To determine whether two given figures are similar, and to use similarity to find missing lengths.
Similar figures have the same shape, but not necessarily the same size.
Congruence and Similarity. Similar Two shapes are similar if their corresponding angles are equal and their corresponding sides are in proportion.
2.5: Similar Figures. What is a Similar Figure? Figures that have the same shape, but not necessarily the same size. Two figures are similar when:

Sec. 6–2 Similar Polygons. Figures that are similar (~) have the same shape but not necessarily the same size. Angles are congruent, Sides are proportional.
Objective: You will learn how to determine if a number is a perfect square and how to find the square root of perfect squares.
When figures have the same size and shape we say they are congruent. In this lesson I will focus on congruent triangles.
