How do you find the area of two similar triangles?
The ratio of the area of two similar triangles is equal to the square of the ratio of any pair of the corresponding sides of the similar triangles. For example, for any two similar triangles ΔABC and ΔDEF, Area of ΔABC/Area of ΔDEF = (AB)2/(DE)2 = (BC)2/(EF)2 = (AC)2(DF)2.
What is the relationship between the perimeter of two similar triangles?
Note: The ratios of corresponding sides of the two triangles are in equal if they are similar. The perimeter of the triangle is equal to the sum of their sides.
How do you find the ratio of the perimeter of similar figures?
ratio of their perimeters is equal to the ratio of their corresponding side lengths. the ratio of their areas is equal to the square of the ratio of their corresponding side lengths.
What is the perimeter of two triangles?
Perimeter = 30 cm. Example 3: What is the missing side length of a triangle whose perimeter is 40 cm and two sides are 10 cm each? Length of two sides is the same i.e. 10 cm….Read More:

How do you find similar areas?
Similar areas and volumes
- We already know that if two shapes are similar their corresponding sides are in the same ratio and their corresponding angles are equal.
- When calculating a missing area, we need to calculate the Area Scale Factor.
- Area Scale Factor (ASF) = (Linear Scale Factor) 2
- The figures below are similar.
How do you find the perimeter of two triangles?
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.
Is the perimeter of similar triangles proportional?
Just as their corresponding sides are in the same proportion, perimeters and areas of similar polygons have a special relationship. Perimeters: The ratio of the perimeters is the same as the scale factor. You square the ratio because area is a two-dimensional measurement.
