Q. If triangle ABC is similar to triangle DEF, and the lengths of sides AB and DE are 6 cm and 9 cm respectively, what is the ratio of the areas of the triangles?
A.
2:3
B.
3:2
C.
4:9
D.
9:4
Solution
The ratio of the areas of similar triangles is the square of the ratio of their corresponding sides. (6/9)² = (2/3)² = 4/9.
Q. If triangle ABC is similar to triangle DEF, and the lengths of sides AB and DE are 4 cm and 8 cm respectively, what is the ratio of the areas of the triangles?
A.
1:2
B.
1:4
C.
2:1
D.
4:1
Solution
The ratio of the areas of similar triangles is the square of the ratio of their corresponding sides. (4/8)^2 = (1/2)^2 = 1/4.
Q. If triangle DEF is similar to triangle GHI, and the lengths of DE and GH are 4 cm and 8 cm respectively, what is the ratio of the areas of the two triangles?
A.
1:2
B.
1:4
C.
1:8
D.
1:16
Solution
The ratio of the areas of similar triangles is the square of the ratio of their corresponding sides. (4/8)^2 = (1/2)^2 = 1/4.
Q. If triangle DEF is similar to triangle XYZ and the sides of DEF are 3 cm, 4 cm, and 5 cm, what are the lengths of the corresponding sides of triangle XYZ if the ratio of similarity is 2:1?
A.
6 cm, 8 cm, 10 cm
B.
3 cm, 4 cm, 5 cm
C.
1.5 cm, 2 cm, 2.5 cm
D.
4 cm, 5 cm, 6 cm
Solution
If the ratio of similarity is 2:1, then the sides of triangle XYZ will be 2 times the sides of triangle DEF, giving 6 cm, 8 cm, and 10 cm.
Q. If triangle DEF is similar to triangle XYZ, and the sides of DEF are 4 cm, 6 cm, and 8 cm, what is the ratio of the sides of triangle XYZ if the shortest side is 2 cm?
A.
1:2
B.
2:3
C.
1:3
D.
2:4
Solution
The ratio of the sides of similar triangles is constant. If the shortest side of DEF is 4 cm and XYZ is 2 cm, the ratio is 2:3.
Q. If triangle GHI is similar to triangle JKL and the length of GH is 5 cm and JK is 10 cm, what is the ratio of their corresponding sides?
A.
1:2
B.
2:1
C.
1:1
D.
5:10
Solution
The ratio of corresponding sides of similar triangles is equal to the ratio of any two corresponding sides. Therefore, the ratio is 5:10, which simplifies to 1:2.
Q. If triangle GHI is similar to triangle JKL and the length of side GH is 5 cm while side JK is 10 cm, what is the ratio of the areas of the two triangles?
A.
1:2
B.
1:4
C.
2:1
D.
4:1
Solution
The ratio of the areas of similar triangles is the square of the ratio of their corresponding sides. (10/5)^2 = 2^2 = 4, so the ratio of the areas is 1:4.
Q. If triangle GHI is similar to triangle JKL and the sides of triangle GHI are 3 cm, 4 cm, and 5 cm, what is the ratio of the sides of triangle JKL if the longest side is 10 cm?
A.
2:1
B.
3:2
C.
5:2
D.
4:1
Solution
The ratio of the longest sides is 10 cm to 5 cm, which simplifies to 2:1. Therefore, the sides of triangle JKL are in the ratio 2:1.
